The ULTRAPEN PTBTx App is a GUI and communication application for use with Myron L Company's wireless ULTRAPEN PTBTx pocket testers. The ULTRAPEN PTBTx and App converts your iOS device into an accurate, reliable, fast and simple to use measurement and data storage device that is ideal for any water quality application.

The PTBT app replaces the standard LCD display, typical to most pocket testers, with a wireless transceiver that transmits measurements to a currently paired iOS device and displays them in large, easy-to-read characters. There are no bothersome wires to interfere with quickly moving from sample to sample and the paired mobile device can be held safely away from the liquid samples being measured.

The app's GUI allows the user to:

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

Download a 7 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.
