The COM-100 meter from HM Digital is a waterproof EC/TDS meter and thermometer for water quality testing. It can also be used for hydroponics, sewage regulation, aquaculture, pools, spas, in boilers and cooling towers, in laboratories and for ecological and scientific tests, etc.
Functions:
- Measurement of electrical conductivity (EC).
- Measurement of the number of dissolved particles (TDS)
- Temperature measurement
- Four scales: µS, mS, ppm 0.5 (NaCl) scale, 0.7 (442™) scale.
- Automatic temperature compensation (ATC) with three temperature coefficients
- Display in degrees Celsius and Fahrenheit
- Digital calibration (push button) to any point within the measuring range
- Automatic shut-off function, data storage function and low battery indicator
- Display: large and easy-to-read LCD screen with simultaneous temperature display
- Replaceable sensor (model SP-C1)
- Waterproof housing (IP-67)
- Factory calibrated: the COM-100 meter is calibrated with a 1413 µS solution
