Digital Insulation Resistance Meter (10kV 2TΩ Megohmmeter)
General Information:
EPR50C Digital insulation resistance meter also known as megohmmeter, high voltage insulation resistance tester, etc., for the insulation resistance test. The instrument has a large LCD screen gray backlit display, data storage, data access, alarm, automatic shutdown and other functions. At the same time, it also has the function of measuring AC voltage absorption ratio and polarization index of DC voltage. The machine is beautiful and upscale, has a wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.
EPR50C has a shockproof, dustproof, moisture-proof structure and is a commonly used and indispensable instrument for telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity 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.
EPR50C Digital insulation resistance meter consists of medium and large scale integrated circuits. The output power of the watch is large, and the output voltage level is a lot (with 6 voltage levels). Rated insulation test voltage range 250V ~ 10kV, insulation resistance measurement range 0.01MΩ ~ 2000GΩ. DC voltage measurement range 0 ~ 1000V, AC voltage measurement range 0 ~ 750V.
