Deskripsi produk Kyoritsu Earth Resistance & Resistivity Tester 4106
- Earth resistance measurement with six ranges covering measurements from 0.001 to 200k.
- Earth resistivity() 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 via USB adaptor (Model 8212-USB) by using software KEW Report which are included.
- Robust design with IP54 protection.
