Kyoritsu KEW 6041BT Pen-Type Insulation & Earth Resistance Tester
Product Description
This multifunction insulation and earth resistance tester offers four insulation test ranges (50 / 125 / 250 / 500 V). When 500 V is selected, a red backlight provides a clear high-voltage warning. The auto discharge function safely releases any residual charge after measurement, and a live-wire warning uses a red backlight and buzzer to prevent measurement when voltage exceeds the safety threshold.
For earth resistance, the tester features 0–2000 Ω auto-ranging and a test current of 2 mA or less to avoid tripping earth leakage breakers. A live-wire warning is activated above 30 V and locks earth resistance measurements until the line is safe. Comparator functions for both insulation and earth resistance use a red backlight and buzzer to alert when readings fall below or exceed preset thresholds, which can be customized via a dedicated app.
The voltage measurement function supports up to 440 V, including three-phase line-to-line measurements, with true RMS for accurate results even on distorted waveforms and automatic AC/DC detection. Additional features include live-wire warning during insulation and earth testing, audible comparator alerts when the display is not visible, customizable ranges and thresholds through the app, four interchangeable tip pins (three types included as standard: standard, long, and molded), an optional L-shaped probe ideal for elevated distribution boards, and built-in Bluetooth communication to save measurement data to tablets and smartphones.
