HM Digital - Pro Series COM-100 Pen Style TDS/EC/Temp Meter

Brand: HM Digital

HM Digital Pro Series COM-100 Pen Style TDS/EC/Temp Meter

The HM Digital COM-100 is a waterproof Professional Series pen meter that measures electrical conductivity (EC), total dissolved solids (TDS) and temperature in one handheld unit. It reads in four scales - uS, mS, ppm on the 0.5 (NaCl) scale and ppm on the 0.7 (442) scale - with automatic temperature compensation, so operators get a fast, dependable check of nutrient strength and water purity.

Use the COM-100 to spot-check nutrient reservoirs, irrigation water, RO permeate and source water throughout indoor cultivation and controlled-environment agriculture facilities. The IP-67 housing is submersible and floats, push-button digital calibration works at any point within the meter's range, and the sensor is user-replaceable (model SP-C1) when it wears out.
