Ultrapen PTBT1 and PTBT2










ULTRAPEN PTBT2 pH and Temperature Pen

The Myron L Ultrapen PTBT2 is an accurate, easy-to-use pH meter and temperature tester in s durable aircraft aluminum case. The Ultrapen PTBT2 has the same range and accuracy as an Ultrameter II but fits in your pocket. readings and calibration are easy. If you’re a pool service tech, hydroponics grower, or water quality consultant, you’ll love using the PTBT2…for a long time to come.

A free app takes advantage of Apple’s iOS graphical user interface to provide easy-to-read displays and a simple-to-use interface. The Bluetooth link means that there are no wires getting in the way when moving quickly between samples and that paired mobile devices can be held safely away from liquids.

Advanced features include: automatic temperature compensation; stable microprocessor-based circuitry; user-intuitive design and a rugged, waterproof housing.
The Ultrapen PTBT2 measures pH and temperature with one-, two- and three-point calibration options.

With the Ultrapen OS app, each Ultrapen PTBTx can be given a unique name stored in the Ultrapen’s memory so it is easily identifiable no matter what mobile device is used. Measurement locations can be programmed as GPS locations that are automatically selected when the user is close to a specific measurement local, or non-GPS locations, which are ideal for applications where the sample sites are too close together for the GPS to discriminate.

Through the app, items such as Ultrapen settings, sample temperatures, Ultrapen name and measurement locations can be saved to the mobile device’s memory. Records can be exported via the mobile device’s email function as either .csv, .xls, .xlsx formatted files or using a proprietary, encrypted format. Stored measurements can be sorted or filtered and then emailed or deleted without affecting other records stored in the memory.
The Ultrapen PTBT3 with ORP and temperature measurement, Ultrapen PTBT4 with free chlorine equivalent and temperature measurement, and an Android-compatible app are all coming soon.

Easily connect to any active ULTRAPEN PTBTx pocket tester by one-touch selection from a list of available testers. Connection screen ONLY shows PTBTx pocket testers and ignores other Bluetooth devices.

Download a 14 character name into each ULTRAPEN PTBTx so that it is easily identifiable no matter what mobile device it is used with.

Program locations either as GPS related locations (automatically selected whenever the user is close to a specific measurement local), but also as non-GPS related locations (ideal for applications where sample sites are too close to each other for the GPS to discriminate).

Store Measurement Data and Calibration History that include:
– Measurement Value.
– UltraPen ID / Name.
– Location (programmable as both GPS and Non-GPS related locations)

Data records are:
– Sortable
– Exportable in .xls; .xlsx, .csv format as well as an encrypted, secure Myron L Company proprietary format.
– Can be filtered so that subsets of records can be deleted or exported without affecting other records stored in the device’s memory.

Performs reliably for me every day April 27, 2014

Reviewer: Ron W., consultant from Huntington Beach CA
I purchased two Myron PT2 Ultrapens for pH and temperature monitoring in June this year and I use them 5 days a week without any problems whatsoever. I monitor pH and temperature on a Biotrickling filter foul air scrubber in a remote location and the Ultrapen performs reliably for me every day. I will be looking to Myron to purchase other instruments as the need arises.

The pH unit that works! April 13, 2014

Reviewer: Coree Coppinger from Milwaukee, WI, US
The other hand held meters varied in price from about 18.00 to 170.00, yet they preform the same: inaccurate, slow, leaked and turn itself off before the calculation was finished. All instructions were performed as noted by directions and videos.

A small field pH unit that was accurate and could be counted on. I relish in it’s simplicity and accuracy. The bottom rubber cap has a sponge inside of it to hold the storage solution, this is smart, although the push and twist is difficult with a flexible rubber cap. This could be better designed with a hard twist cap and a O RING in the inside of the cap. I am so happy to find a unit that preforms as it is supposed to, and is dead on with the solutions. The only thing to test next is how well it preforms with time. Yes this Myron L UltraPen PT2 is worth the money. After the ill fated experiences with the other brands being sold on the market you will find the price is much easier to swallow. It works and is accurate, that is all I ask!
