Kewtech 4202 Bluetooth Digital Earth Resistance Clamp Meter

Kewtech

Measure earth resistance with no auxiliary earth spikes needed Range from 0.05 to 1500Ω True RMS Kewtech 4202 Bluetooth Digital Earth Resistance Clamp Meter Details Quick and easy - simply clamp the KEW 4202 around an earth conductor and carry out earth/ground resistance measurements! Also suitable for measurements of leakage current, the KEW 4202 can measure current from 100mA to 30A and resistance from 20Ω to 1200Ω. You can rely on the clamp to always produce high accuracy results thanks to built-in true RMS and a built-in filter function which will increase immunity to excess electrical noise. This clamp meter is Bluetooth enabled and can wirelessly interface with Android devices. Using Kewtech's free app, real-time measurements can be transferred, saved and shown on your Android device, complete with measurement, GPS location and date/time data. This will help you to understand exactly when and where a measurement was taken (ideal for days when you'll be testing multiple points). Kewtech 4202 Earth Clamp Meter Key Features Measure earth resistance without the need to use auxiliary earth spikes Measurement range from 0.05 to 1500Ω True RMS leakage or phase current readings from 0.1mA to 30.0A Filter function increases immunity in electrically noisy environments Noise warning appears when large amount of electrical noise is present Bluetooth enabled wireless transmission to Android devices Data hld function 32mm jaw opening Automatic power off when left idle Backlit screen What's Included?
