product description
Digital insulation resistance tester, also known as megohmmeter and high-voltage insulation resistance meter, is used for testing insulation resistance. This instrument has large-screen LCD gray-white backlight display, data storage, data review, alarm, automatic discharge, charging, automatic shutdown and other functions. It also has the function of measuring DC voltage AC voltage absorption ratio and polarization index. The whole machine is beautiful and high-end, with wide measuring range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, large output power and strong anti-interference ability.
The digital insulation resistance tester has a shockproof, dustproof and moisture-proof structure and is adaptable to harsh working environments. It is commonly used in telecommunications, electric power, meteorology, machine rooms, oil fields, mechanical and electrical installation and maintenance, and industrial enterprise departments that use electricity as industrial power or energy. An essential instrument. It is suitable for measuring the insulation resistance values of various insulating materials and transformers, motors, cables and electrical equipment.
