XHMR-5000A Digital high voltage Insulation resistance tester
Digital insulation resistance meter, also known as megger, high voltage insulation resistance tester, etc., is used for insulation resistance testing.
The instrument has the functions of gray and white backlight LCD large screen display, data storage, data query, alarm, automatic shutdown and so on. At the same time, it also has the function of measuring DC voltage AC voltage absorption ratio and polarization index. The whole machine is beautiful and high-grade, with wide measuring range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance and strong anti-interference ability. And with shockproof, dustproof and moistureproof structure, it is a commonly used and indispensable instrument in the industrial enterprise departments of telecommunications, electric power, meteorology, computer room, oil field, electromechanical installation and maintenance, and industrial enterprises that use electric power as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
The digital insulation resistance meter is composed of medium and large scale integrated circuits. This meter has large output power and multiple output voltage levels (5 voltage levels). The rated insulation test voltage range is 250~5000V, and the insulation resistance measurement range is 0.01MΩ~200GΩ. The measuring range of DC voltage is 0~1000V, and the measuring range of AC voltage is 0~750V.
