Tds ec meter com-80 manual

Water treatment professionals use our TDS meter to monitor the status of the RO membrane in home and commercial filter systems. You can do it too. First, measure the TDS of unfiltered water. Then measure the RO water. The RO should be removed at least 90% of the TDS. Most people replace the RO membrane when the RO removes about 70% of the TDS. The EC reading is affected by temperature. Three op-tions are available for temperature compensation: 1. Automatic (ATC): the EC probe features a built-in temperature sensor, which provides the temperature reading to automatically compensate the EC and TDS measurements (from 0.0 to 100.0°C), also using the selected reference temperature. 2. The temperature correction coeffcient (β) is fixed at 2 %/°C and allows for automatic temperature compensated measurements of EC and TDS. These meters are calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41 mS/cm (1413 µS/cm) or 1500 ppm.
