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.
FEATURES
Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
UPGRADED: Four scales: µS, mS, ppm, ppt (mS and ppt are new)
Three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl).
Automatic Temperature Compensation (ATC) using three temperature coefficients
Digital Calibration (push button) 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 buttons, rather than a screwdriver.
Includes a cap, batteries and lanyard.
