Digital high-voltage insulation resistance meter (megohmmeter)
Function: Insulation resistance test, voltage test rated voltage (V): 250; 500; 1000; 2500; 5000 insulation resistance range (G): 0.01M~200G DC voltag
Product details
FR3025E digital high-voltage insulation resistance meter, 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 strong anti-interference ability.

Moreover, it has shockproof, dust-proof, and moisture-proof structures, and is suitable for harsh working environments. It is a commonly used and essential instrument for 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.
