Earth insulation tester
This instrument has LCD large screen grey backlight display, data storage, data reference, alarm, automatic shutdown and other functions. Tegelijkertijd, it also has the function of measuring DC voltage and AC voltage absorption ratio and polarization index. The machine is beautiful and high-grade, wijde selectie, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.
And with shock-proof, stofdicht, moisture-proof structure, adapt to the harsh working environment, is telecommunications, electric power, meteorology, computer room, oil field, mechanical and electrical installation and maintenance and the use of electricity as an industrial power or energy industry commonly used instruments. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
