About this item
Kyoritsu 4106 .The Kyoritsu KEW 4106 is a hand-held digital instrument engineered for precise measurement of earth resistance and soil resistivity. Housed in a rugged, IP54-rated case, it integrates a microcomputer to automate complex calculations, enabling fast and reliable readings even in electrically noisy environments. Its dot-matrix LCD with backlight ensures clear visibility of results in low-light or dusty conditions. Equipped with versatile wiring options, the KEW 4106 supports 2-, 3-, and 4-wire fall-of-potential resistance tests, as well as Wenner 4-pole resistivity measurements. Users can select or auto-select one of four test frequencies (94 Hz, 105 Hz, 111 Hz, 128 Hz) to minimize interference, while the built-in FFT-based filtering stabilizes readings under challenging site conditions.. Data management is streamlined: up to 800 results can be stored and later transferred to a PC via the supplied USB optical adapter and KEW Report software. Additional conveniences include residual-lead resistance nulling, automatic power-off, battery-voltage check, and alerted warnings for high auxiliary-spike resistance or earth-voltage interference
