Overview
Enviro Test Construct Megger ohm meter is used for insulation resistance test. This instrument has a large LCD screen gray backlit display, data storage, data review, alarm, automatic shutdown and other functions. At the same time, it also has the function of measuring absorption ratio and polarization index of AC voltage and 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. It also has a shockproof, dustproof, moisture-proof structure, and adapts to the harsh working environment. It is a commonly used and indispensable 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. It is composed of medium and large-scale integrated circuits. The output power of the watch is large, and the output voltage level is more (has 5 voltage levels). Rated insulation test voltage range 100 V to 2500 V insulation resistance measurement range 0.01 MΩ to 200 GΩ. DC voltage measurement range 0 to 1000 V AC voltage measurement range 0 to 750 V.
