The P612 Conductivity Meter delivers precise water quality testing with a large backlit LCD display and advanced microprocessor intelligence. It measures conductivity, TDS, salinity, and resistivity across wide ranges, with auto-calibration, eight standard solution recognition, and automatic temperature compensation. IP57 waterproof construction, 200-set data storage, and low-power AA battery operation make it ideal for field and lab use. Accuracy: ±1.5% FS overall.
