Digital High Voltage Insulation Resistance Meter, also known as Megohmmeter, High Voltage Insulation Resistance Tester, is used for insulation resistance testing. This meter has LCD large screen gray backlight display, data storage, data access, alarm, automatic shutdown and other functions. At the same time also has the measurement of DC voltage AC voltage absorption ratio and polarization index function. The whole machine is beautiful and high-grade, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.
And has a shockproof, dustproof, moisture-proof structure, adapt to the harsh working environment, is the telecommunications, electric power, meteorology, engine room, oil fields, electromechanical installation and maintenance and the use of electric power as an industrial power or energy source of industrial enterprises commonly used and essential instrumentation. It is suitable for measuring the resistance value of various insulating materials and insulation resistance of transformers, motors, cables and electrical equipment.
Composed of medium and large-scale integrated circuits. This meter has large output power and many output voltage levels (5 voltage levels). Rated insulation test voltage range 100 ~ 5000V, insulation resistance measurement range 0.01 ~ 200GΩ. DC voltage measurement range 0 ~ 1000V, AC voltage measurement range 0 ~ 750V.
