The PTBT1 is a pocket-sized water quality tester for measuring conductivity, TDS, salinity, and temperature, designed for use with the Myron L® Company PTBTX2™ mobile app. It features an anodized aircraft aluminum body, IP67 and NEMA 6 waterproofing, and operates on a single N-type alkaline battery. The device offers automatic temperature compensation to 25°C, with measurement ranges of 1-9999 µS/ppm for conductivity and TDS, 0.0010-9.999 ppt for salinity, and 0-71°C for temperature, all with ±1% accuracy after wet calibration. It stores measurements with time, date, and location data, and exports via email. Physical dimensions are 17.15 cm in length and 1.59 cm in diameter, weighing 55 g. The unit includes a protective cap, pocket clip, holster, lanyard, and quick start guide, and comes with a one-year limited warranty excluding the battery.
All Myron L® handheld instruments are factory calibrated with NIST traceable Standard Solutions having specific conductivity/ppm values. Myron L® Company Standard Solutions are made under strictly controlled conditions using reagent grade salts. These salts are mixed with deionized water having a resistivity of at least 5 megohms-cm purity.
Myron L® Company Standard Solutions have an accuracy of ±1% based on values published in the International Critical Tables and traceable to the National Institute of Standards and Technology.
The conductivity Standard Solutions and pH Buffers listed below are used for factory calibration. Regular use of these solutions is recommended to ensure specified instrument accuracy. Frequency of conductivity recalibration depends upon use, but once every month should be sufficient for an instrument used daily. pH models, depending upon use, should be recalibrated with pH 7 Buffer every 1-2 weeks, and checked with pH 4 and/or 10 Buffers at similar intervals. pH Sensor Storage Solution is recommended for keeping the pH sensor wet. Myron L® solutions are available in quart/1 ltr., gallon/3,8 ltr. and 2 oz./59 ml plastic bottles, ready to use. (Custom value standards only offered in gallon/3,8 ltr. size bottles.)
