Kyoritsu 4106 Earth Resistance & Resistivity Tester

  • Model: KE 4106
  • Shipping Weight: 0.9kg
  • Manufactured by: KYORITSU

RM9,290.00

Add to Cart:

High test current up to 80mA yielding resolution of 0.001Ω on 2Ω range.

Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements.

Automatic and Manual selection of the Test Current Frequency in four bands (94/105/111/128Hz). In Automatic mode, KEW 4106 will select the most suitable Frequency.

Several sub-results can be shown on the display: Resistance of the Auxiliary Earth Spikes, Frequency of Test Current, Voltage and Frequency of Interference (noise), Residual Resistance Rk, etc.

Warning for excessive noise and high Auxiliary Earth Spikes resistance.

 


 

Large Graphic Display with backlight for readings in poorly illuminated areas.

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 using the "KEW Report" software and a USB adaptor (Model 8212-USB) which are included.

Robust design with IP54 protection.
