HM Digital (COM-100) Waterproof EC-TDS-Temperature Combo Meter-Monitor
COM-100 Waterproof EC/TDS/Temperature Combo Meter
The HM Digital COM-100 combines EC, TDS, and temperature measurement in one waterproof device. With 0-9990 µS EC range, 0-8560 ppm TDS range, and ±2% accuracy, this meter eliminates the need for screwdriver calibration with digital push-button adjustment. Three calibration standards (KCl, 442™, NaCl) with non-linear conversion factors ensure precision across applications.
Built for field and lab precision
Triple measurement display
Simultaneous EC, TDS, and temperature readings on large LCD screen with auto-ranging from 0.1 to 10 µS/ppm resolution
Digital calibration system
Push-button calibration with three standard options (KCl, 442™, NaCl), each using precise non-linear conversion factors
Automatic temperature compensation
ATC with three adjustable coefficients ensures accurate readings from 0-80°C (32-176°F) without manual correction
Submersible waterproof housing
Fully waterproof design for direct immersion testing in tanks, streams, treatment facilities, and field environments
Detachable platinum electrodes
Replaceable probe design with platinum sensors for durability and long-term accuracy in harsh water conditions
Auto-off and data hold
Power-saving auto-off function, data-hold for recording measurements, and low-battery indicator for reliable operation
Professional and consumer water testing
The HM Digital COM-100 is ideal for reverse osmosis system monitoring, aquaculture water quality management, hydroponic nutrient solution testing, pool and spa maintenance, colloidal silver production, laboratory analysis, wastewater regulation compliance, boiler and cooling tower treatment, and ecological field testing. Factory calibrated with 1413 µS solution and recalibrates digitally without tools. Includes protective cap, three 1.5V button cell batteries, and lanyard. Dimensions: 18.5 × 3.4 × 3.4 cm (7.3 × 1.3 × 1.3 inches). Weight: 90.7g (3.2 oz) without case.
HM Digital meters are factory calibrated and tested to ensure accuracy out of the box for immediate professional use.
