Insulation Resistance Testing Instrument
Darui Electric recommends:
Insulation Resistance Testing Instrument（Insulation resistance testing instrument）also known as digital insulation resistance tester, megohmmeter, intelligent insulation resistance tester, etc., suitable for insulation testing in maintenance, repair, testing and verification of various electrical equipment.The insulation resistance tester is suitable for insulation testing in maintenance, repair, testing and verification of various electrical equipment. The insulation resistance scale lines are uniform and clear, facilitating accurate reading. Simple operation, easy to carry. Low power consumption, powered by 8×1.5V (AA, R6) batteries, with long usage time. Has battery capacity check function.
Product Features
1. For the insulation test of the meter, for 5400, the maximum measurable at 500V is 20GΩ, at 1000V up to 40GΩ, at 2500V up to 100GΩ;
For 5500 type, at 2500V up to 100GΩ, at 5000V up to 200GΩ;
For 5600 type, at 5000V up to 200GΩ, at 10000V up to 400GΩ;.
2. The rated output voltage is maintained for 5400 type with load resistance as low as 4MΩ/8MΩ/20MΩ;
For 5500 type, it is 20MΩ/40MΩ;
For 5600 type, it is 40MΩ/80MΩ, which enables the meter to accurately measure lower insulation impedance.
3. Automatically switching high and low range dual scale indication, colored scales are easy to read, and have LED display of corresponding colors.
4. The whole machine adopts ABS plastic shell portable design, with strong anti-interference ability, compact structure, and beautiful appearance.
5. The meter adopts ultra-thin tension wire meter head, with strong seismic resistance.
6. Dual AC/DC use, built-in rechargeable battery and intelligent charging module, the whole machine has large output power (C type).
7. It is an ideal testing instrument for measuring insulation resistance of transformers, mutual inductors, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
