Main highlights

Three different modes: Switch between output of results in TDS (ppm) or EC (μs) at the touch of a button. In addition, the device is able to indicate the temperature of the measured liquid in Celsius or Fahrenheit.
Ready for immediate use: Our conductor meter is already pre-calibrated from the factory. After switching it on, you can start measuring immediately. Post-calibration is possible at any time via the screw on the back of the device.
Quick measurement of solvent materials: The gauge is able to measure the electrical conductivity of the water (EC). From this value, the number of solids TDS (Total Dissolved Solids) can also be determined.
Perfect readability guaranteed: Thanks to the practical hold function, measuring results can be frozen for easy reading. The brightly illuminated display makes it much easier to operate the conductivity meter especially in the dark or under strong light incidence.
Accurate measurements: The MEASURY TDS&EC meter measures the conductivity (EC) of 0 - 9,990 μs/cm and the TDS value of 0 - 9,990 ppm. Resolution: 1μs/ppm from 0 - 999, 10 μs/ppm from 1,000 - 9,990. The accuracy of the measuring device is ± 2 %.
