⚡ At a Glance
- • Measurement Range: 0.1MΩ to 2000MΩ with selectable 250V, 500V and 1000V test voltages
- • Best for: Electricians, maintenance technicians and HVAC engineers performing insulation checks
- • Not ideal for: Laboratory users who require extensive data logging and PC integration
High-precision insulation resistance tester with selectable test voltages and automatic safety alerts. Field-ready kit includes a backlit 3.5-inch display, protective cover and detachable strap.
Dependable insulation readings - Thanks to 0.1MΩ–2000MΩ range and ±4% accuracy
Resistance measurement covers 0.1MΩ to 2000MΩ with 1999 counts and ±4% accuracy, and sampling occurs about three times per second. Auto-zero function corrects offsets and stabilises low-value readings.
Consistent figures make trend checks and pass/fail decisions straightforward on site. Clear numeric stability reduces the need for repeated measurements.
Safer voltage checks - With AC/DC measurement and audible high-voltage alerts
AC voltage measurement extends to 750V with approximately ±1.0% accuracy while DC measurement goes to 1000V with about ±0.5% accuracy. A high-voltage indicator light and buzzer emit warnings if dangerous voltage is present and a continuity buzzer signals short conditions.
Quickly confirm whether circuits are live before performing insulation tests. Audible and visual alerts help avoid accidental testing on energized conductors.
Practical on-site use - With large backlit display, data hold and included accessories
A 3.5-inch backlit LCD makes readings visible in poor light and a data hold function freezes values for later recording. Built-in 100mA/60V resettable fuse and a 72cm detachable strap add protection and portability, while two test leads and two crocodile clips are supplied.
Easy-to-read measurements and basic protection speed up fault finding in cramped or dim spaces. Supplied leads and cover mean immediate use without extra purchases.

❓ Frequently Asked Questions
Q: Can the meter measure both insulation resistance and voltage?
A: Yes. Insulation resistance measurement ranges from 0.1MΩ to 2000MΩ with selectable 250V, 500V and 1000V test voltages, and AC/DC voltage can be measured up to 750V AC and 1000V DC.
Q: How does the meter warn about unsafe voltages?
A: A high-voltage indicator light and an audible buzzer alert when dangerous voltage is present, and a continuity buzzer sounds for short circuits or very low resistance values.
Q: What accessories are included and is there a warranty?
A: Two test leads, two crocodile clips, a detachable strap and a protective cover are supplied, and the unit comes with a 365-day quality warranty.
