What Stands Out
Versatile Measurements
The HM Digital Com-300 efficiently measures pH, TDS, EC, and temperature, making it ideal for aquariums, hydroponics, and laboratory applications with comprehensive aquatic health insights.
User-Friendly Display
Equipped with a large LCD display, the meter allows for easy reading of results, ensuring accurate monitoring for both professionals and hobbyists in a variety of environments.
Durable Design

Detalles de producto
- 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.

“The prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services. My experience with the "Ubuy" website was excellent. I purchased a PRS USA Swamp Ash Special guitar, and it arrived in just 11 days. The shipping service was fantastic, and the product arrived in perfect condition. What I particularly appreciated about the site is that the prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services.”
