The COM-300 is an advanced waterproof combo meter with superior accuracy. The meter measures four : pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS) and temperature. Features include 2 different conductivity conversion factors to convert EC to TDS using the 0.5 (NaCl) or 0.7 (442TM), as well as selectable modes for measurements in the S, mS and ppm scales. The meter incorporates automatic temperature compensation (ATC) to accommodate for discrepancies in temperature that would naturally occur, and also features digital calibration for easy and precise calibration that will yield better results.

Measures electrical conductivity (EC), total dissolved solids (TDS), temperature.

UPGRADED: Four scales: μS, mS, ppm, ppt

Three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl).

Automatic Temperature Compensation (ATC) using three temperature coefficients

Waterproof housing (IP-67 rating)

Measurement Range: 0-9990 μS; 0-8560 ppm; 0-9.99 mS; 0-8.56 ppt

Digital Calibration (push on) to any point within the meter's range

Auto-off function, data-hold function and low-battery indicator

Display: large and easy-to-read LCD screen includes simultaneous temperature reading.

Replaceable Sensor (model SP-C1)

Factory Calibrated: The COM-100 meter is calibrated with a 1413 μS solution. The meter can be recalibrated with digital calibration using the push ons, rather than a screwdriver.
