Description
This insulation resistance tester delivers stable and accurate measurements for electrical maintenance tasks. The large 80 × 50 mm LCD panel provides clear visibility, while the 50-segment analog bar graph helps users observe trends in real time. With a maximum reading of 4000 counts, the tester improves measurement clarity and reliability.
The device supports auto-range mega ohm measurement at 250V, 500V, and 1000V, which makes insulation testing simple and efficient. The built-in continuity buzzer (<4Ω) allows quick wiring checks during troubleshooting. Its fast sampling rate updates the digital display at 2.5 times per second and the bar graph at 10 times per second for responsive performance.
Designed for field use, this tester runs on eight AA batteries and features a compact, portable body. It complies with IEC61557, ensuring dependable operation for electricians, technicians, and maintenance engineers who require accurate insulation and continuity testing.
