 EARTH CLAMP TESTER_KEW 4202
EARTH CLAMP TESTER_KEW 4202
  • Real time measurements can be transferred, shown and saved on Android device (up to 100 measurements)
  • Saved data includes measurement, GPS location and date & time; Easy to check on map "When" and "Where" the measurement was made
  • Comparator function on Android device informs when the measured value is lower/higher than the preset value
Earth /Ground resistance and Leakage current measurement functions
  • The earth resistance from 0.05 to 1200 Ω can be measured without the auxiliary earth spikes in multi-earthing systems
  • True RMS leakage or phase current readings from 0.1mA to 30.0A provides vital additional information in earthing networks
  • Filter function offers increased immunity to electrical noise and a Noise mark appears in excessively high noisy environments
