General Information:
EPR50A Digital insulation resistance meter also known as megohmmeter,high voltage insulation resistance tester, etc., for the insulationresistance test. The instrument has a large LCD screen gray backlit display,data storage, data access, alarm, automatic shutdown and other functions. Atthe same time, it also has the function of measuring AC voltage absorptionratio and polarization index of DC voltage. The machine is beautiful andupscale, has a wide range, high resolution, convenient operation, easy tocarry, accurate, reliable, stable performance, strong anti-interference ability.
EPR50A has a shockproof, dustproof, moisture-proof structureand is a commonly used and indispensable instrument for telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installationand maintenance, and industrial enterprises that use electricity as industrialpower or energy. It is suitable for measuring the resistance value of variousinsulating materials and the insulation resistance of transformers, motors,cables and electrical equipment.
EPR50A Digital insulation resistance meter consists of medium and large-scale integrated circuits. This meter has high output power and many output voltages levels (there are 6 voltage levels). The rated insulation testvoltage range is 250V ～ 5kV, and the insulation resistance measurement range is 0.01MΩ ～ 2000GΩ. DC voltage measurement range is 0 ~1000V, AC voltage measurement range is 0 ~ 750V.
