Portable insulation resistance meter HZJY-5K-I 5kV

• Test voltage ranges: 500V, 1000V, 2500V, 5000V • Insulation resistance up to 5TΩ @ 5kV • Short-circuit current: 2–5mA adjustable (10mA optional) • Battery life: 6 hours @ 5000V/100MΩ • Capacitance test range: up to 20µF • Safety standard: IEC 61010-1 CAT.IV 600V, IEC 60529 IP64 • Weight: 3kg, size 26 × 20 × 16cm The HZJY-5K-I insulation resistance tester is built to international safety standards, delivering reliable performance for field use. It automatically displays polarization index (PI), dielectric absorption ratio (DAR), leakage current, and capacitance values. With strong anti-interference capability, it ensures accurate results even under 2mA disturbance current. The instrument features fast capacitive discharge, avoiding manual discharge after cable or equipment testing. A digital filter minimizes external noise effects, while multiple protections and fuse prompts further enhance safety. Powered by rechargeable lithium batteries or AC supply, it provides up to six hours of continuous operation at full load. Its intuitive insulation resistance simulation column improves testing efficiency, while precise voltage and current measurements meet wide application needs. Compact and lightweight at 3kg, the HZJY-5K-I is a portable, durable, and high-precision tool widely applied in power utilities, substations, and industrial electrical equipment testing.
