GM-5kV Adjustable Insulation Resistance Tester, setting a new benchmark for precision and adaptability in critical electrical system maintenance. Designed for demanding field and lab environments, this advanced instrument tackles insulation integrity challenges with unprecedented flexibility and intelligence.
Key Features & Innovations
1、Truly Adjustable High Voltage (50V to 5kV):
The Game-Changer: Ditch fixed voltage limitations. The GM-5kV offers continuousor steppedvoltage selection from 50V up to a robust 5,000V DC.
Why It Matters: Test low-voltage control circuits (24V/50V), standard 250V/500V/1kV installations, andhigh-voltage equipment (transformers, switchgear, cables up to 35kV) with a SINGLE tool. Perfect for diverse infrastructure – factories, utilities, renewables.
2、Advanced PI & DAR Testing (Polarization Index / Dielectric Absorption Ratio):
Smarter Diagnostics: Automatically calculates PI & DAR ratios – the gold standards for identifying moisture ingress, contamination, and aging in insulation. Goes beyond simple "pass/fail."
Predictive Power: Reveals trendsin insulation degradation, enabling proactive replacement before catastrophic failure occurs.
3、Massive Range & High Accuracy:
Wide Reach: Measures insulation resistance from teraohms (TΩ) down to kilohms (kΩ), covering everything from pristine new cables to deteriorating motors.
Confidence in Results: Delivers high accuracy (±[Spec]%) even at extreme ends of its range, backed by strict calibration standards.
4、Operator-Centric Design:
Intuitive Interface: Large backlit LCD displays all critical parameters simultaneously – test voltage, measured value, PI/DAR, timer, alarms.
Set-and-Forget Testing: Programmable test timers (1-99 min) and auto-discharge circuits enhance safety and productivity.
Rugged & Portable: Built to IP54 standards for dust/water resistance, with ergonomic grips for safe handling during high-voltage tests. Long-life Li-Ion battery supports full-day operation.
5、Data Intelligence & Connectivity:
Stop Guessing, Start Analyzing: Stores 1000+ test results with timestamps. Review trends directly or download via USB/Bluetooth® for in-depth reports and compliance audits (IEC, IEEE, NETA standards).
Voltage Alarm: Audible/visual alerts if actual test voltage deviates significantly from the set value, ensuring test validity.
Core Benefits
1、Unmatched Versatility: Replace multiple fixed-voltage testers with one future-proof device. Adapt on-the-fly to any application.
2、Deeper Diagnostic Insight: PI/DAR ratios reveal the true "health" of insulation, not just its immediate status.
3、Enhanced Safety: Robust construction, auto-discharge, and clear warnings protect technicians.
4、Boosted Productivity: Faster setup, automated tests, and easy data management slash inspection time.
5、Cost Efficiency: Reduce equipment inventory and prevent costly downtime through predictive maintenance.
