Waterproof EC/TDS/Temp Combo Meter HMDCOM100

Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. The COM-100 is a professional level EC/TDS meter at an unbeatable price.

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

UPGRADED: Four scales: S, mS, ppm, ppt (mS and ppt are new)

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

Automatic Temperature Compensation (ATC) using three temperature coefficients

Waterproof housing (IP-67 rating)

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

Digital Calibration (push button) to any point within the meters 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 S solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.

Includes a cap, batteries and lanyard.
