Use your Bluetooth®-enabled mobile device with the user-intuitive, Myron L® Ultrapen PTBTX2™ app to measure, store and export water quality data (includes time, date, and location) for Free Chlorine Equivalent (FC^E) and Temperature! The UltrapenX2™ PTBT4 is the fast accurate way to determine the killing power of free chlorine species in water. It employs a proprietary predictive ORP algorithm to determine free available chlorine levels at the actual pH of water, so you know your chlorine treatment is effective. Following colorimetric measurement requirements may increase chlorine usage unnecessarily or give a false impression of clean and safe water. The PTBT4 is designed with more high-performance features including proprietary sensor design; accuracy of up to ±0.3 ppm FC^E™; calibration with pH and ORP standard solutions; automatic temperature compensation; user-selectable LIVE and HOLD modes; rugged aircraft aluminum body; durable, epoxy encapsulated electronics; easy app integration; IP67 dust-tight and waterproof up to 1 meter / NEMA 6 submersible.

PTBT4 Measurement Modes include: Hold (default), which captures and displays a stabilized reading, and LIVE, which continuously displays real-time readings.
