KYORITSU KEW 4202

Category: Earth Tester

Quick Overview:

Tag: #Earth Clamp Testers

Various useful functions are available on Android devices using Bluetooth communication

• 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
