HM Digital COM-360 Professional 4-in-1 pH/EC/TDS/Temp Meter | Replaceable Sensor
HM Digital COM-360 Professional 4-in-1 pH/EC/TDS/Temp Meter
The HM Digital COM-360 is a professional-grade multi-parameter water quality meter measuring pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature — all in one rugged, water-resistant handheld. Trusted by hydroponics growers, aquaculture professionals, lab technicians, pool operators, and water treatment specialists worldwide.
Key Features
4-in-1 Measurement: pH, EC, TDS, and Temperature in a single meter — no need to carry multiple instruments.
Five Measurement Scales: pH, µS, mS, ppm 0.5 (NaCl), and ppm 0.7 (442™) for maximum application flexibility.
Automatic Temperature Compensation (ATC): Three selectable temperature coefficients for accurate readings across varying conditions.
Replaceable Sensor (SP-CP): Detachable platinum electrodes and pH glass sensor with reference tube — replace the sensor, not the meter.
Factory Calibrated: pH, EC, and TDS ready out of the box; digital push-button calibration to any point within range.
Large Simultaneous LCD Display: Reads primary parameter and temperature at the same time.
Water-Resistant Housing: Built for field and lab use.
Smart Field Features: Auto-off, data-hold, and low-battery indicator.
