ISO 17025: General Requirements for the Competence of Testing and Calibration Laboratories
CE Certification(Conformité Européenne)

Dual-Parameter Precision
- Simultaneous Insulation Resistance & Leakage Current Testing: Eliminates the need for separate instruments.
- 100 kΩ–10 TΩ Range: Covers residential to utility-scale PV module testing (10⁵ Ω–10¹³ Ω).
Ultra-High Accuracy
- <1 GΩ: ±1%, 1–10 GΩ: ±3%, ≥10 GΩ: ±5%: Ensures compliance with IEC 61215’s stringent insulation requirements.
- 1% Voltage Accuracy: 1.0–1,000 VDC output with 0.1 V/1 V step adjustments.
Multi-Speed Testing
- 55 Readings/Second (High-Speed Mode): Ideal for production line QC.
- 3 Readings/Second (Full-Speed Mode): Maximizes measurement resolution for R&D.
Safety First
- 30 mA Max Charging Current: Prevents arc-flash risks during high-voltage testing.
- Overvoltage Protection: 1,200 VDC surge rating for transient stability.
Smart Diagnostics
- AI-Powered Failure Analysis: Flags insulation breakdown patterns and PID risks.
- Auto-Ranging: Optimizes test voltage (50–1,000 VDC) based on module specs.

Non-Destructive Testing (NDT): Preserves sample integrity with <10 nA leakage current.
Laser-Guided Probe Placement: Ensures precise contact on textured module surfaces.
Dynamic Calibration: Auto-corrects for temperature/humidity drift during testing.
Emergency Shutoff: Dual redundant safety circuits with E-stop button.
Glovebox Compatibility: Oxygen/moisture levels <0.1 ppm for sensitive chemistries.
