ES3035+ Digital Insulation Resistance Tester
Digital Insulation Resistance Tester · Megohmmeter · 5000V · 2000GΩ
The digital insulation resistance tester, also known as a megohmmeter or high-voltage insulation resistance tester, is used for insulation resistance measurement. This instrument features a large LCD screen with gray-white backlight display, data storage, data review, alarm, and auto power-off functions. It also measures DC voltage, AC voltage, absorption ratio, and polarization index. The instrument is elegantly designed with a wide range, high resolution, easy operation, and portability. It is accurate, reliable, stable in performance, and has strong anti-interference capability. With its shockproof, dustproof, and moisture-proof structure, it is an essential instrument commonly used in telecommunications, power, meteorology, machine rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises utilizing electricity as industrial power or energy. It is suitable for measuring the resistance values of various insulating materials and the insulation resistance of transformers, motors, cables, and electrical equipment.
