Description

Hioki IR4053-10
- Safely and accurately measure PV insulation resistance even while generating solar power
- Built-in PV dedicated function, display measurements in 4 seconds
- Five ranges (50/125/250/500/1000V) built in for normal insulation resistance measurement
Digital Insulation Tester
The Hioki IR4053 is a digital insulation resistance tester for photovoltaic generation systems. Measure insulation resistance accurate and safely without being affected by generated solar power and identify the value in just 4 seconds.

Measurement not affected by generating PV
The IR4053, which was designed for PV, can accurately measure insulation resistance without being affected by the generating PV.

Accurate and safe measurement without creating shorts
Normally, to accurately measure the insulation resistance of a generating PV, one needs to short the measured circuit. That’s not necessary with the IR4053. (Left figure: Short-circuit switch).

Displays measurement in 4 seconds
The IR4053 displays the measured value just 4 seconds after starting measurement. After the first display, the displayed value is updated each second. Comfortably carry out swift measurements.
