HM Digital COM-300 pH/EC/TDS/Temperature Meter

The COM-300 from HM Digital's Professional Series is a waterproof combo meter that measures four parameters: pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature. It can test the acidity or alkalinity of almost any liquid, provided the liquid contains less than 50% alcohol and has a conductivity of at least 10 µS (5 ppm TDS on the 0.5 scale).

EC is read in µS or mS, and TDS in ppm using pre-programmed, non-linear conversions for 0.5 (NaCl) or 0.7 (442™) solutions selected by the user. Automatic temperature compensation refers every reading to 25 °C, and the temperature is shown on the LCD at the same time as the pH or EC/TDS reading.

The meter is factory calibrated to a 1413 µS KCl solution and to pH 7.0. pH is recalibrated by push-button auto-calibration to 4, 7 or 10 pH with manual fine tuning, and EC/TDS can be calibrated digitally to any point within the range. The IP-67 housing is submersible and floats, and the sensor (Part # SP-C3) is detachable and replaceable.

Key Features

Measures pH, EC, TDS and temperature; temperature shown simultaneously with pH or EC/TDS
Modes: pH, EC (µS), EC (mS), TDS ppm 0.5 (NaCl) and TDS ppm 0.7 (442™)
Accuracy: ±0.1 pH, ±2% EC/TDS, ±1 °C/°F
Automatic temperature compensation to 25 °C (ATC range 1–50 °C); each TDS factor uses its own ATC coefficient and the EC modes use the KCl coefficient
Digital push-button calibration: pH auto-calibration to 4, 7 or 10 pH with fine tuning, EC/TDS to any point within the range, plus temperature calibration
Hold function, auto shut-off after 5 minutes, low-battery indicator and warning symbol
IP-67 waterproof housing, submersible and floats
Detachable, replaceable sensor (Part # SP-C3)
Powered by 2 × AAA batteries, approximately 100 hours of use
Manufacturer warranty: one year on the meter, six months on the SP-C3 sensor
