EARTH RESISTANCE & RESISTIVITY TESTER

KEW 4106

Earth Resistance & Resistivity Tester

Earth resistance measurement with six ranges covering measurements from 0.001 Ω to 200 kΩ
Earth resistivity (ρ) measurement is automatically calculated after having set the distance between Auxiliary Earth Spikes (Wenner method)
Automatic and Manual selection of the Test Current Frequency in four bands of 94/105/111/128Hz
In Automatic mode KEW 4106 will select the most suitable Frequency
Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements
Up to 800 measurement results can be saved in the memory and recalled on the display
The stored results can be transferred to a PC by using USB adapter (MODEL 8212-USB) and the special software "KEW Report"
Robust design with IP54 protection
