Product Details
- HM Digital COM-300 is a waterproof combo meter that measures 4 water parameters in one device: pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature. As a reliable pH meter and TDS meter in one, it is well suited for hydroponic systems, water gardens, and ponds. The water tester features 2 conductivity conversion factors for converting EC to TDS using either the 0.5 (NaCl) or 0.7 (442) factor, with selectable measurement modes across µS, mS, and ppm scales. Automatic temperature compensation (ATC) accounts for natural temperature variations to keep readings consistent, while digital calibration makes it straightforward to fine-tune for precise results. The sump-type screened inlet design adds to its practical, field-ready build. Whether you need a dependable pH test tool or full water quality monitoring, HM Digital delivers accurate multi-parameter readings in a single handheld unit.
