HM Digital COM-80S EC-TDS HydroTester for Water Testing

The HM Digital COM-80S HydroTester is a compact handheld water quality meter designed to measure electrical conductivity (EC), total dissolved solids (TDS), and temperature in water. It is suitable for checking drinking water, laboratory water, aquariums, hydroponic solutions, pools, spas, water treatment systems, and other applications where dissolved solids and conductivity need to be monitored. The meter provides readings in µS, mS, ppm, °C, and °F, with selectable TDS conversion scales. The COM-80S also features automatic temperature compensation, digital push-button calibration, data hold, auto-off, and low-battery indication. Its water-resistant pen-style design makes it convenient for both field and routine laboratory use Key Features - Measures TDS, EC, and temperature - EC measurement in µS and mS - TDS measurement in ppm - Selectable 0.5 NaCl and 0.7/442 TDS scales - Automatic Temperature Compensation - Digital push-button calibration - Large easy-to-read LCD - Simultaneous temperature display - Data hold function - Auto power-off - Low-battery indicator - Water-resistant housing - Factory calibrated at 1413 µS - Protective cap included - Compact, portable design
