HM Digital COM-80 EC/TDS HydroTester Conductivity and TDS Pen Meter

HM Digital COM-80 EC/TDS HydroTester

The COM-80 from HM Digital's EC/TDS HydroTester Series is an advanced, economically priced and reliable EC/TDS pen meter. It measures electrical conductivity (EC) and total dissolved solids (TDS) on four selectable scales – µS and mS for EC, and ppm on the 0.5 (NaCl) and 0.7 (442™) conversion factors for TDS – which makes it excellent for nutrient testing.

EC is measured from 0 to 9990 µS or 0 to 9.9 mS, and TDS from 0 to 5000 ppm (0.5 scale) or 0 to 8560 ppm (0.7 scale), with an accuracy of ±2%. Automatic Temperature Compensation (ATC) is built in, and the large, easy-to-read LCD shows the temperature (1–80 °C) simultaneously with the reading.

Versatile and durable, the meter is ideal for hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers and drinking water, as well as water treatment, food and beverage and industrial applications. It is factory calibrated with a 1413 µS solution and can be recalibrated digitally to any point within its range.
