III. Normal Operation

Before you take a reading, make sure the pen is clean, calibrated and in the appropriate measurement mode. The sample solution must also be within the specified measurement range. Keep all foreign material away from the sample to avoid contamination.

Note: If you cannot dip the pen in the sample solution, pour the sample into a clean container. If you don’t have a sample container and need to test a vertical stream of solution, use the scoop.

The following table explains what the LED Indicator Light signals mean and gives the duration of each signal.

LED Indicator Light Signal Meaning duration

Rapid Flashing Dip pen in solution 6 sec

Slow Flashing Measurement in process 10-20 sec

Solid Light Note measurement value 6 sec

CAUTION: To measure solution at the extremes of the specified temperature range, allow the pen to equilibrate by submerging the cell in the sample solution for 1 minute prior to taking a measurement.

1. Rinse the pen 3 times by submerging the cell in fresh sample solution and swirling it around.

2. Remove pen from solution, then press and release the push button. Firmware version will be displayed, then current measurement mode.

3. Grasp the pen by its case with your fingers positioned between the display and the pen cap to avoid sample contamination.

4. While the LED flashes rapidly, dip the pen in fresh sample solution so that the cell is completely submerged. If you do not submerge the cell in solution before the flashing slows, allow the pen to power off and retake the reading.

5. While the LED flashes slowly, swirl the pen around to remove bubbles, keeping the cell submerged. Keep the pen at least 1 inch (2½ cm) away from sides/bottom of container, if applicable.

6. When the LED turns on solid, remove the pen from solution. The display will alternate between the measurement and temperature readings. Note the readings for your records.

*Note: This procedure applies to the Ultrameter, PoolPro, TechPro, and D-6 Dialysate meter.

IMPORTANT: Always “zero” your Ultrameter II with a pH 7 buffer solution

before adjusting the gain with acid or base buffers, i.e., 4 and/or 10, etc.

a. pH Zero Calibration (6PFCE)

1. Rinse sensor well and cell cup 3 times with 7 buffer solution.

2. Refill both sensor well and cell cup with 7 buffer solution.

3. Press

pH

 

 

 

 

to verify the pH calibration. If the display shows 7.00, skip the pH

Zero Calibration and proceed to pH Gain Calibration.

4. Press

CAL key

 

 

 

 

 

to enter calibration mode. “CAL”, “BUFFER” and “7” will appear on the display.

display

 

 

 

 

 

 

 

Displayed value will be the uncalibrated sensor.

NOTES: If a wrong buffer is added (outside of 6-8 pH),“7” and “BUFFER

will flash, and the Ultrameter II will not adjust.

The uncalibrated pH value displayed in step 4 will assist in determining

the accuracy of the pH sensor. If the pH reading is above 8 with pH 7

buffer solution, the sensor well needs additional rinsing or the pH sensor

is defective and needs to be replaced.

5. Press

Up

 

 

 

 

or

Down

 

 

 

 

until the display reads 7.00.

NOTE: Attempted calibration of >1 pH point from factory calibration will

cause “FAC” to appear. This indicates the need for sensor replacement

or fresh buffer solution. The “FAC” internal electronic calibration is not intended to

replace calibration with pH buffers. It assumes an ideal pH sensor. Each “FAC”

indicates a factory setting for that calibration step (i.e., 7, acid, base).

You may press

CAL key

 

 

 

 

 

to accept the preset factory value, or you may

reduce your variation from factory setting by pressing

Up

 

 

 

 

or

Down

 

 

 

 

6. Press to accept the new value. The pH Zero Calibration

is now complete. You may continue with pH Gain Calibration or

exit by pressing any measurement key.

b. pH Gain Calibration (6PFCE)

IMPORTANT: Always calibrate or verify your Ultrameter II with a pH 7

buffer solution before adjusting the gain with acid or base buffers, i.e.,

4 and/or 10, etc. Either acid or base solution can be used for the 2nd

point “Gain” calibration and then the opposite for the 3rd point. The

display will verify that a buffer is in the sensor well by displaying either

Acd” or “bAS”.

1. The pH calibration mode is initiated by either completion of the

pH Zero Calibration, or verifying 7 buffer and pressing the

CAL key

 

 

 

 

 

key twice while in pH measurement mode.

2. At this point the “CAL”, “BUFFER” and “Acd” or “bAS

will be displayed (see Figures 7 and 8).

Capture

 

NOTE: If the “Acd” and “bAS” indicators are blinking, it indicates

an error and needs either an acid or base solution present in the sensor

well.

3. Rinse sensor well 3 times with acid or base buffer solution.

4. Refill sensor well again with same buffer solution.

5. Press

Up

 

 

 

 

or

Down

 

 

 

 

until the display agrees with the buffer value.

6. Press

CAL key

 

 

 

 

 

to accept the 2nd point of calibration. Now the

display indicates the next type of buffer to be used.

Single point Gain Calibration is complete. You may continue for the 3rd

point of Calibration (2nd Gain) or exit by pressing any measurement key.

Exiting causes the value accepted for the buffer to be used for both acid

and base measurements.

To continue with 3rd point calibration, use basic buffer if acidic buffer

was used in the 2nd point, or vice-versa. Again, match the display to the

known buffer value as in step 2 and continue with the following steps:

7. Repeat steps 3 through 6 using opposite buffer solution.

8. Press

CAL key

 

 

 

 

 

to accept 3rd point of calibration, which completes the Calibration procedure.

Fill sensor well with Sensor Storage Solution and replace protective cap.

My 750 Series II Monitor or Monitor/Controller display shows a 1, then a space, then a decimal point. What does this mean?
This is an over-range condition that can be fixed by performing an Electronic calibration of the circuit board. Please see directions in the Operations Manual or follow this brief review of Electronic Calibration. Hook up a Multi-Meter to the R+ and R- leads located at the top of the circuit board, switch the Multi-Meter to DC volts, push the Full Scale Push to Test button and read the DC voltage on the Multi-Meter. While pushing the Full Scale Push to Test button, adjust the CAL screw on the circuit board until the Multi-Meter reads 9.95-10.00 VDC. The display on the Myron L Monitor or Monitor/Controller should now read Full Scale.

How do I pick the correct range module for my Monitor or Monitor/Controller?
You must pick a range module that covers your 2/3 of your operating range. If you pick a range module that is too broad, then your accuracy will suffer or it will not show a number on the display. For example, if your operating range is 100-150 microsiemens, a range module of 0-200 microsiemens (-115) would be a good choice. A range module of 0-5,000 microsiemens (-123) would not be a good choice for this application.

Why does my displayed number fluctuate?
There is air or air bubbles around the sensor or the sensor is not properly installed. Tap on the sensor body to dislodge air bubbles or loosen securing nut to release trapped air. The sensor tip must be in the flow of water.

My device connected to the dry contact relay does not work and has no power. What do I do?
The Myron L dry contact relay does not draw power from the circuit board. You must supply the power to the relay to power your device.

Why is the display number on the Monitor or Monitor/Controller negative?
This is the offset that is being display and is caused when the sensor is not hooked up or is hooked up and sitting in air.

Why is the displayed number on the Monitor or Monitor/Controller half the reading than it should be?
This is caused when the 115/230 VAC switch is set to 230VAC when in fact it should be switched to 115 VAC.

Does the Aquaswitch I require any other device to help it switch banks?

Yes, the AquaSwitch I requires a Monitor/Controller in order to switch banks.

What is the recommended method to mount a Conductivity or Resistivity sensor?
The optimal method to mount the sensor is in the end of a tee with the water flowing directly into the tip of the sensor and flowing up and away at a 90 degree angle. Please see the 750 Series II Operations Manual for complete instructions.

I want to use my Monitor or Monitor/Controller for another application but the water quality is a totally different range. Can my existing unit be changed?
Our 750 Series II Conductivity/TDS and Resistivity Monitors and Monitor/Controllers can be “Re-Ranged” with a new range module to meet you changing needs. Simply un-plug the old range module and plug in the new range module into the circuit board. Refer to page 8 of the Operations Manual to see the Range Selection guide and to see if any minor modifications are necessary.

How can I tell what the model number of my Monitor or Monitor/Controller is?
The module number is circled on the transformer and printed on the back of the case.

pH and ORP Sensors for Inline Monitor/Controllers: MyronLMeters.com

Posted by 19 Mar, 2014

TweetAll Myron L pH and Oxidation Reduction Potential or ORP sensors are combination pH/reference, or ORP/reference. These sensors are designed to operate with Myron L 720 Series II pH and ORP Monitor/controllers. Each sensor has a built-in isolated preamplifier that guarantees accurate and reliable measurements — completely eliminating ground-loops and noise issues. The preamp allows […]

All Myron L pH and Oxidation Reduction Potential or ORP sensors are combination pH/reference, or ORP/reference. These sensors are designed to operate with Myron L 720 Series II pH and ORP Monitor/controllers. Each sensor has a built-in isolated preamplifier that guarantees accurate and reliable measurements — completely eliminating ground-loops and noise issues. The preamp allows for longer distances between the sensor and our Monitor/controller without the loss of accuracy or reliability due to cable capacitance, resistance, or noise.

Our preamp is so simple and low cost that we build it right into the sensor, thus allowing for a truly sealed sensor system — no O-rings to become damaged and leak, no BNC connectors to corrode and cause unreliable readings. It is actually no more expensive than the BNC connectors and coax cable it replaces.

All pH sensors include a built-in Temperature Sensor for automatic Temperature Compensation (TC). The TC may be disabled, requirements per USP, or if a separate temperature device is required for your SCADA system.

All bodies are made of Schedule 80 Chlorinated Polyvinyl Chloride (CPVC) or Ryton®* Polyphenylene Sulfide (PPS) to withstand the demanding requirements of most applications. Choice of double ended 1/2” or 3/4” MNPT body allows for ease of installation in either in-line or submersion applications. All Myron L sensors are completely encapsulated and sealed to keep out moisture and to assure long life under demanding conditions. Just install and use. Overall length is ~165 mm/6.5 in. Standard cable length is 3 meters/ 10 ft. Sensors may be ordered with 8 meter/25 ft. or 30 meter/100 ft. lengths. Cable may be extended simply and without problems. We recommend a junction box to protect the splice.

For in-line use, simply install sensor into female threaded fitting or tee. For submersion use, simply install into user supplied pipe coupling and extension pipe.

• Built-in isolated preamp guarantees accurate, trouble
free operation.

• Temperature Sensor built-in for automatic Temperature
Compensation (may be disabled as required).

• All sensors are double ended MNPT for simple in-line
or submersion applications.

• All sensors are pH/reference, or ORP/ reference, or a
combination of the two.
• CPVC/Ryton® bodies assure compatibility in most
applications.

• All sensors are completely encapsulated and sealed.

• Sensor cable may be extended simply, without problems.

• All ORP sensors have an extended tip Platinum
electrode except “F” models.

• Heavy Duty “F” models may be installed in ANY
direction, including inverted.

Sensor specs

 

 

 

 

 

 

In the specific descriptions below, substitute ORP for pH where
applicable.

General Purpose Single Junction
Low Cost In-line/Submersion pH and ORP Sensors.
The Single Junction “S” reference sensor is used for simple, non-demanding applications. It uses Potassium Chloride (KCI) reference gel. Response time, generally 95% in one second. For intermittent use up to 100°C/212°F @ 3,45 bar/50 psi. Twelve (12) month shelf life. This is our most economical sensor.

Special Purpose Double Junction
Low Cost In-line/Submersion pH and ORP Sensors.
The Double Junction “D” reference sensor is used in more demanding applications where “poisoning” of the reference is a possibility or a concern. It uses Potassium Nitrate (KNO3) gel where the reference meets the solution. This sensor is an ideal, cost effective alternative for demanding environmental applications not requiring the added advantages of the Heavy Duty Flat Tip sensor listed below. Response time, generally 95% in one second. When in doubt it is best to select a Double Junction sensor. Twelve (12) month shelf life. This sensor is the ideal, most cost effective Double Junction sensor on the market.

Low Conductivity

Low Cost In-line/Submersion pH and ORP Sensors.
The Low Conductivity “LC” sensor is recommended when the pH or ORP of low conductivity (low ionic strength) solutions must be measured. This sensor utilizes a porous polyethylene Double Junction with a low molar (0.1) KCI gel in the reference meeting the solution. This low molar reference more closely matches the low ionic strength of the solution, which allows more stable readings and cuts down in the contamination of the solution being measured. The LC sensor is recommended for use in RO/DI applications with solutions less than 100 µM/
µS/ppm. Twelve (12) month shelf life. This sensor is made for special, low conductivity applications.

Heavy Duty
Low Cost In-line/Submersion pH and ORP Sensors.
The Heavy Duty “F” utilizes a FLAT-TIP self cleaning sensor (flat glass in place of a round bulb) for use where the most demanding applications are found, such as wastewater. The flat tip will last longer in most abrasive and/or oily solution environments. These sensors utilize a HDPE (High Density Polyethylene) Double Junction reference with a high temperature
— chemical resistant acrylamide gel. Response time, generally 95% in five seconds. For continuous use 100°C/212°F @ 3,45 bar/50 psi, 81°C/178°F @ 5,86 bar/85 psi, and 76°C/169°F @ 6,9 bar/100 psi. Six (6) month shelf life. This sensor may be installed in ANY direction including INVERTED, and is simply the BEST sensor for tough applications.

Note: High flow reference junctions (HDPE, Kynar and Teflon) are available on above models upon special order. These special junctions will help keep the reference from clogging as easily — in some applications, however, they will deplete the reference gel more quickly, and thus have a shorter shelf/use life.

STORAGE/SHELF LIFE
ALL pH and ORP sensors are life limited. For this reason, it is recommended that extra sensors be kept on hand for all process applications. To obtain the maximum life, ALWAYS store sensor in pH/ORP Sensor Storage Solution when not in use. DO NOT allow sensor to dry out.

A.           Conductivity/TDS Standard Solutions

Your Ultrameter II has been factory calibrated with the appropriate Myron L NIST traceable KCl, NaCl, and our own 442™ standard solutions. Most Myron L conductivity standard solution bottles show three values referenced at 25°C: Conductivity in microsiemens/ micromhos, the ppm/TDS equivalents (based on our 442 Natural Water™) and NaCl standards. All standards are within ±1.0% of reference solutions.

1.            Potassium Chloride (KCl)

The concentrations of these reference solutions are calculated from data in the International Critical Tables, Vol. 6. The 7000 µS is the recommended standard. Order KCL-7000 here: http://www.myronlmeters.com/Myron-L-KCL-7000-uS-32-oz-calibration-solution-p/s-kcl-7000q.htm

2.            442 Natural Water™

442 Natural Water Standard Solutions are based on the following salt proportions: 40% sodium sulfate, 40% sodium bicarbonate, and 20% sodium chloride, which represent the three predominant components (anions) in freshwater. This salt ratio has conductivity characteristics approximating fresh natural waters and was developed by Myron L over four decades ago. It is used around the world for measuring both conductivity and TDS in drinking water, ground water, lakes, streams, etc. 3000 ppm is the recommended standard. Order 442-3000 here: http://www.myronlmeters.com/442-3000-ppm-TDS-calibration-solution-32oz-quart-p/s-442-3000q.htm

BATTERY CHECK

Most Myron L analog meters have a battery indicator glow light visible through the small hole on the lower right-hand corner of the meter face plate. If this light fails to glow when the black button is pressed, replace both batteries.

BATTERY REPLACEMENT
To replace the batteries detach the battery connectors. Pull on the plastic straps to remove the batteries. Replace with fresh zinc carbon or alkaline 9 volt batteries. Reinsert the plastic straps to secure batteries.

CELL CUP
Self-conditioning of the built-in electrodes occurs each time the button is pressed with a sample in the cell cup. This ensures consistent results each time. With some samples a small downward swing of the pointer is a result of this conditioning action. This action is powerful and removes normal films of oil and dirt. However, if very dirty samples – particularly scaling types – are allowed to dry in the cell cup, a film will build up. This film reduces accuracy. When there are visible films of oil, dirt, or scale in the cell cup or on the electrodes, scrub them lightly with a small brush and household cleanser. Rinse out the cleanser, and the meter is ready for accurate measurements. pH SENSOR The unique pH electrode in your pDS meter is a nonrefillable combination type which features a porous Teflon* liquid junction (covered by U.S. Patent No. 4128468). It should never be allowed to dry out (see pH MEASUREMENT). If it does, the sensor can sometimes be renewed by soaking in a saturated potassium chloride (KCI) solution for several days. “Drifting” can be caused by a film on the sensor bulb. Use a liquid cleaner such as Windex™ or fantastik™ to clean it. The sensor buIb is very thin and delicate. Excessive pressure during cleaning may break it. Leaving high pH (alkaline) solutions in contact with the pH sensor for long periods of time can damage it. Rinsing such liquids from the pH compartment and moistening it with 4 buffer or tap water will extend its useful life. Samples containing chlorine, sulphur, or ammonia can “poison” any pH electrode. If it is necessary to measure the pH of any such sample, thoroughly rinse the pH sensor with clean water immediately after taking the measurement. Any sample element which will reduce (add an electron to) silver, such as cyanide, will attack the reference electrode. Replacement sensors are available from MyronLMeters.com. *™ DuPont Company

WATER INSIDE THE METER
Your Myron L meter is a rugged instrument and will withstand water exposure around its cell, meter movement, and switches. However, care should be taken to keep water from leaking in around the bottom cover. It is not sealed (to prevent condensation from forming). If the water is relatively clean (i.e., tap water or better), and there are only a few drops inside the meter, dry it as described below. Large amounts of water, or corrosive or very dirty solutions will almost certainly damage the meter movement or electronics. Such meters should be returned to the Myron L Company for repair.

To dry your meter:
1. Shake excess water out of the inside of the meter.
2. Dab the exposed surface dry with an absorbent cloth or tissue. Avoid pushing any water into the Calibration Controls or the switches.
3. Air dry the meter in a warm area with the bottom cover off. Allow several hours for thorough drying. If the water entered through a leak in the case or cell, or if the instrument shows erratic readings or other unusual behavior, return it for servicing.
