The company says its new TechPro™ series of pH/conductivity/TDS/temperature instruments are designed for water treatment testing and a variety of other applications. Specific uses include boilers, cooling towers, reverse osmosis systems, and calibration of online controllers. Ranges are 0-14 pH, 0-20 mS/ppt (in three auto ranges), and 32º-160ºF, according to the company. Accuracy is ±0.5 pH, ±1% for each conductivity/TDS range, and ±1ºF, it says.
