Kyoritsu Kew 4106 Earth Resistance and Specific Resistance Tester
4 Pile measuring earth megger
It is an ideal device for large grounding systems.
Kew 4106 uses a test current of 80 mA (max), providing high resolution up to 1mΩ in 2Ω stage.
Optimum test current frequency
4 bands (94/105/111/128 Hz) test current frequency and advanced filtering method, which can be selected automatically or manually, reduces interference during the test.
It measures very low ground resistance measurements accurately and accurately. Soil specific resistance (ρ) is calculated automatically
Kew 4106, sticks 0.1 m. at intervals of 1.0 to 30.0 m. It allows distances up to variable.
Separate sub-results and parameters can be displayed on the screen
It shows the resistance of ground bars, the test current frequency, the voltage and frequency of interference and residual resistance.
Memorizing, Recalling Memory and Uploading to Computer
Memorizes the results of 800 measurements and displays the information in the memory on the screen.
You can transfer this information to any computer using the "Kew Report" software and USB adapter provided.
It stimulates the parasitic and high resistance of auxiliary earth bars visually.
It has international IP 54 standard and is not affected by dust and moisture.
