Professional 5-Range Insulation Tester
Measure insulation resistance from 0.1MΩ to 200GΩ with 5 selectable test voltages (100V/250V/500V/1000V/2500V). Designed for professional use in motor testing, cable inspection, industrial maintenance, and electrical safety checks.
Advanced DAR & PI Diagnostics
Automatically calculates DAR (60s/15s) and PI (10min/1min) with one button. Easily assess insulation condition, detect aging, and identify potential faults for proactive maintenance.
Instant PASS/FAIL Evaluation
Set custom thresholds and get real-time PASS/FAIL results. Simplifies testing workflows, improves efficiency, and ensures consistent quality and safety verification.
Multifunction & Smart Features
Built-in multimeter functions with AC/DC voltage measurement (up to 750V AC / 1000V DC) and continuity test (buzzer alert). Stores up to 100 readings with Data Hold, features a backlit LCD for low-light visibility, auto power-off, and low battery indicator.
Pro-Grade Safety & Durable Design
IEC/EN 61010-1 certified with CAT III 1000V / CAT IV 600V protection. Rugged double-insulated housing with anti-drop silicone cover ensures durability in harsh working environments.
