Introducing our advanced digital Insulation Resistance Tester, designed for efficient and accurate electrical measurements. This device uses a low-loss, high-ratio inductance energy storage DC voltage converter to convert 12V to DC 250V/500V/1000V. It features a digital LCR Bridge for precise resistance evaluation, making it ideal for insulation resistance testing. Key Features: Wide Measuring Range: Up to 2000MΩ at 1000V with an accuracy of ±(4% of reading + 2 digits). Large LCD Display: 90 x 48mm with backlight, capable of displaying up to "1999". Convenient Functions: Includes data hold, test lock, and auto power off for ease of use. Low Power Consumption: Consumes less than 300mW during no-load measurement. Stable Performance: Perfect for testing insulation resistance in motors, cables, electrical and telecommunication equipment.
