The Ultrapen PT1 is designed to be very reliable and requires only infrequent calibration. The factory recommends calibrating each measurement mode you use once monthly. However, you should check the calibration whenever measurements are not as expected. The PT1 is programmed for 2 calibration options: Wet Calibration or Factory Calibration. Wet calibration is most accurate. But if a high quality standard KCl-1800 µS or 442-3000 ppm solution is not available, the PT1 can be returned to factory settings.

A. Wet Calibration
Use calibration solution specified for measurement mode: Use KCL- 1800 for Cond KCl; Use 442-3000 for tdS 442, SALt 442, tdS NaCl, and SALt NaCl. See Specifications table for 442 solution ppm NaCl equivalent value. Calibrating TDS simultaneously calibrates SALT for the same value and vice versa.
1. Pour calibration solution into a clean container.
2. Rinse the pen 3 times by submerging the cell in fresh calibration solution and swirling it around.
3. Remove pen from solution, then fill the container one more time.
4. Press and release the push button. The LCD will briefly display the firmware version then the current measurement mode. Ensure the PT1 is in the correct solution mode.
5. Immediately push and hold the push button. The display will scroll through “CAL”, “SOL SEL”, “FAC CAL”, “ºCºF TEMP”, and “ESC”. Release the button when “CAL” displays.
6. Grasp the pen by its case with your fingers positioned between the
display and the pen cap to avoid sample contamination.
7. While the LED flashes rapidly, dip the pen in calibration solution so that the cell is completely submerged. If you do not submerge the cell in solution before the fl slows, allow the pen to power off and start over.
8. While the LED flashes slowly, swirl the pen around to remove bubbles, keeping the cell submerged. Keep pen at least 1 inch (2½ cm) away from sides/bottom of container.
9. When the LED light stays on solid, remove the pen from the solution. “CAL SAVED” will display indicating a successful calibration.
Note: If an incorrect solution is used or the measurement is NOT within calibration limits for any other reason, “Error” displays alternately with “CLEAn CEL/CHEC SOL”. Check to make sure you are using the correct calibration solution. If the solution is correct, clean the cell by submerging the cell in a 1:1 solution of Lime-A-Way® and water for 5 minutes. Rinse the cell and start over.
10. Small bubbles trapped in the cell can give a false calibration. Measure the calibration solution again to verify correct calibration. If the reading is not within ±1% of the calibration solution value, repeat calibration.

B. Factory Calibration
If you do not have the proper calibration solution or wish to restore the pen to its original factory settings for any other reason, use the FAC CAL function to calibrate the PT1.
1. Press and release the push button. The LCD will briefly display the firmware version then the current measurement mode.
2. Immediately push and hold the push button. The display will scroll through “CAL”, “SOL SEL”, “FAC CAL”, “ºCºF TEMP”, and “ESC”. Release the button when “FAC CAL” displays.
3. While the display scrolls through “PUSHnHLD” and “FAC CAL”, push and hold the push button until the display scrolls through “SAVEd” and “FAC CAL”, indicating the pen has been reset to its factory calibration.
4. Allow the pen to time out to turn power off.

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.

Fountain Solutions
Accurate fountain (dampening) solution concentration control is essential for consistent, high-quality results in lithography. Low concentration can cause drying on the non-image area of the plate resulting in tinting, scumming, blanket piling, etc. High concentrations, on the other hand, bring about over-emulsification of the ink. This results in weakening of color strength and changes in ink rheology (body and flow properties). Correct concentration will allow the non-image areas of the plate to be appropriately wetted.

Ways to Test

Traditionally, pH was the test relied on to determine fountain solution concentration. Today, however, conductivity testing is recognized as a much more accurate method. Many modern dampening solutions are pH stabilized (or buffered), so only small changes in pH are seen even when dramatic changes occur in solution strength. Conductivity measurement is a fast and easy test which is more indicative of fountain solution concentration than pH. This is true for all neutral, alkaline, and many acid type solutions.

pH is still important, however, with unbuffered acid fountain solutions. Checking both conductivity and pH can provide valuable information. Acid fountain solution is a mixture of gum arabic, wetting agents, salts, acids, buffers, etc. Conductivity will tell you if the proper amount of most ingredients are present, but pH is necessary to check acid concentrations. pH will also determine how effective one ingredient, gum arabic, will be.

Conductivity Testing

What is conductivity? Conductivity is the measurement of a solution’s ability to conduct an electrical current. It is usually expressed in microsiemens (micromhos). Absolutely pure water is actually a poor electrical conductor. It is the substances dissolved in water which determine how conductive the solution will be. Therefore, conductivity is an excellent indicator of solution strength. To properly measure the conductivity of fountain solutions:

Test and write down the conductivity of the water used to prepare the solution.
Mix the fountain solution concentrate with the water, using the manufacturer’s recommendations or as experience dictates.
Measure the conductivity of the mixed solution.
Subtract the water conductivity value obtained in step 1. This is necessary because tap water quality can change from day to day.

The resulting number is an accurate indicator of fountain solution strength. Caution: because alcohol will lower a solution’s conductivity, always test solution conductivity before and after the addition of alcohol.

Determining the best concentration of fountain solution is mostly ‘trial and error.’ It can be very useful to make a graph, recording readings for every one-half or one ounce of concentrate added to a gallon of water. Record readings on a graph with the vertical axis representing conductivity values and the horizontal axis representing ounces/gallon. Such a graph will help ‘fine tune’ your system during future press runs.
For ‘on the spot’ fountain solution tests, Myron L meters are fast, accurate, and reliable. Measurements are made in seconds simply by pouring a small sample of solution into the instrument cell cup and pressing a button. Automatic temperature compensated accuracy and reliability have made our instruments popular in pressrooms worldwide.

pH Testing

Even though pH usually is not the best method to check the concentration of fountain solution, it is still very important and must be checked regularly. The pH of acid dampening solution affects sensitivity, plate-life, ink-drying, etc. Also, pH can change during a run if the paper has a high acid or alkaline content. pH, therefore, must be maintained at the proper level for good printing.

A convenient and accurate way to test pH (as well as temperature) is the waterproof ULTRAMETER II Model 6P or TECHPRO II TH1. The 6P has a 100 reading memory and the TH1 has a 20 reading memory to store test results onsite. The 6P also measures conductivity. All electrodes are contained in the cell cup for protection. Model M6/PH also measures pH and conductivity.

Continuous Control

For continuous monitoring and/or control of fountain solution concentration, we offer a complete series of in-line conductivity instruments. These economical, accurate, and reliable models use a remotely installed sensor and a panel/wall mount meter enclosure. Most contain an adjustable set point and heavy duty relay circuit which can be used to activate alarms, valves, feed pumps, etc. All models contain a 0-10VDC output for a chart recorder or PLC (SCADA) input, if required, (4-20mA output is also available).

The 750 Series II with dual set point option has become quite popular in pressrooms. The two set points allow a ‘safe zone’ for controlling fountain solution concentration.

Litho-Kit

Ultrameter II 6P, 512M5 and M6/PH are available with the useful LITHO-KIT. This accessory includes a foam-lined, rugged all-plastic carrying case with calibrating solutions and buffers. In addition, a syringe to simplify drawing samples and a thermometer for testing fountain solution temperature are also included.

Please note:  These procedures apply to Ultrameters, Pool Pros, Tech Pros, and D-4 and D-6 dialysate meters.

Measuring Conductivity & TDS

1. Rinse cell cup 3 times with sample to be measured. (This conditions

the temperature compensation network and prepares the cell.)

2. Refill cell cup with sample.

3. Press COND or TDS.

4. Take reading. A display of [- - - -] indicates an over range condition.

Measuring Resistivity

Resistivity is for low conductivity solutions. In a cell cup the value may drift from trace contaminants or absorption from atmospheric gasses, so measuring a flowing sample is recommended.

1. Ensure pH protective cap is secure to avoid contamination.

2. Hold instrument at 30° angle (cup sloping downward).

3. Let sample flow continuously into conductivity cell with no aeration.

4. Press RES key; use best reading.

NOTE: If reading is lower than 10 kilohms display will be dashes: [ - - - - ]. Use Conductivity.

If you have further questions, please watch our Ultrameter 6P product overview video here: http://blog.myronlmeters.com/ultrameter-ii-product-review/

 IV. AFTER USING THE ULTRAMETER II

Maintenance of the Conductivity Cell

Rinse out the cell cup with clean water. Do not scrub the cell. For oily films, squirt in a foaming non-abrasive cleaner and rinse. Even if a very active chemical discolors the electrodes, this does not affect the accuracy; leave it alone.
