Profile:

This device adopts the low-voltage shielding principle, integrating control box and voltage doubling cylinder. It features LCD display, automatic polarization compensation and overvoltage/overcurrent protection, enabling convenient and reliable on-site testing without complex wiring.

Features:

Low-voltage shielding technology separates water pipe current from insulation leakage current for accurate measurement
Automatic polarization compensation eliminates polarization potential impact, ensuring stable leakage current reading
LCD display with intuitive parameter setting, test status and result presentation
One-key timing (1-minute) function meets test procedure requirements
Comprehensive protections: overvoltage/overcurrent protection + external zinc oxide overvoltage protector
Integrated design simplifies wiring, reducing equipment weight and operational intensity
Supports both water-passing and water-filled test modes to adapt to different water quality conditions
