ES3025E digital high-voltage insulation resistance tester, also known as megohmmeter or high-voltage insulation resistance tester, is used for testing insulation resistance. This instrument has functions such as LCD large screen gray white backlight display, data storage, data retrieval, alarm, automatic shutdown, etc. It also has the function of measuring the absorption ratio and polarization index of DC voltage and AC voltage. The whole machine is beautiful and high-end, with a wide range, high resolution, convenient operation, easy portability, accuracy, reliability, stable performance, and resistance toDry * capableStrong power.
And it has shockproof, dustproof, and moisture-proof structures, suitable for harsh working environments. It is a commonly used instrument in telecommunications, power, meteorology, computer rooms, oil fields, mechanical and electrical installation and maintenance, as well as industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring the resistance values of various insulation materials and the insulation resistance of transformers, motors, cables, and electrical equipment.

Composed of medium to large-scale integrated circuits. This table has a high output power and multiple output voltage levels (with 5 voltage levels). The rated insulation test voltage range is 100-5000V, and the insulation resistance measurement range is 0.01-200G Ω. The DC voltage measurement range is 0-1000V, and the AC voltage measurement range is 0-750V.
