This instrument is an ideal instrument for testing electrical insulation materials, wires and cables, anti-static engineering resistance measurement and other electrical products insulation resistance. This instrument uses internationally advanced ultra-high resistance and micro-current devices, and has the advantages of high measurement accuracy, strong resolution, strong anti-interference ability, good reading stability, small size, easy to carry and use, and strong battery versatility. This series insulation resistance measuring instruments have been recommended by the Certification Department of Shanghai Cable Research Institute as one of the necessary instruments for production licenses over the years.
The first digital display portable high resistance meter in China, powered by batteries or external power supply, has the characteristics of high measurement accuracy, strong anti-interference ability, good reading stability, etc. The technical performance fully meets the national standards and complies with the relevant standard requirements of "Electrical Performance Test Methods for Wires and Cables Part 5 Insulation Resistance Test" GB/T3048.5-2007 . Thousands of units have been used in laboratories and production sites of wire and cable factories. 31/2 digit digital display (with backlight), basic error: ±1%, built-in timer, can preset measurement time.
