HM Digital Combo COM-100 TDS / EC / Temp. conductometer

The device is designed to measure the total amount of any dissolved in water the substance (ppm. ppt), conductivity (µS, mS) and temperature (° C). To save battery, the device turns off automatically after 10 minutes of inactivity.

measurement of liquid electrical conductivity (EC)
measurement of total dissolved compounds (TDS)
liquid temperature measurement
the meter gives a reading in four scales: µS, mS, ppm, ppt
three different nonlinear EC to TDS conversion factors (KCl, 442TM, NaCl)
automatic temperature compensation (ATC) using three temperature coefficients
waterproof case
measuring range: 0-9990 µS, 0-8560 ppm, 0-9.99 mS, 0-8.56 ppt
digital calibration using buttons to any point within the range of the scale
auto-off battery saving function
memory function of the last reading (hold)
low battery indicator
large, readable LCD display
simultaneous temperature measurement
replaceable sensor (sensor model SP-C1)
factory calibrated using a 1.413 mS solution.
