Chi tiết


Various useful functions are available on Android devices using Bluetooth communication
Free Android software "KEW smart 4202"
is available on "Google Play Store"

  • Supporting Android ver. 2.2 - 4.4
  • WVGA (800 × 480) resolution or higher
  • GPS function
(*) Please search "KEW Smart" in Google Play Store.
Communication charge may be incurred separately to download application.
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 1500 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
