Ideal for all tests of water quality, applications of water purification, the regulation of wastewater, aquaculture, hydroponics, silver colloidal, laboratories and scientific testing, pools and spas, testing the ecology, boilers and cooling towers, water treatment and more.

FEATURES:
Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
Four scales: µS, mS, ppm, ppt (mS and ppt are new). Three different non-linear conversion factors TDS-EC (KCl, 442 TM, NaCl).
Automatic temperature Compensation (ATC) using three temperature coefficients
Waterproof housing (IP-67)
Measurement range: 0-9990 µS; 0-8560 ppm; 0 to 9.99 mS; 0 to 8,56 ppt
Calibration digital (push button) to any point within the range of the meter
The auto power off function, data-hold and low battery indicator
Display: large and easy-to-read LCD screen includes the reading of the temperature at the same time.
Sensor-replaceable battery (model SP-C1)
The COM-100 is calibrated with a solution µS 1413. The meter can be calibrated digital calibration using the push buttons, rather than a screwdriver.
Includes a cap, batteries and a cord.
