Insulation resistance tester, also known as megohmmeter, high-voltage insulation resistance tester, etc., dedicated to the laboratory or on-site insulation testing. The instrument has LCD large screen grey backlight display, data storage, data access, automatic shutdown and other functions. At the same time, it also has automatic calculation of absorption ratio and polarisation index, and automatic storage of 15 seconds, 30 seconds, 1 minute, 10 minutes of data. High resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. And with shockproof, dustproof, moisture-proof structure, is the telecommunications, electric power, meteorology, engine room, oilfield, electromechanical installation and maintenance, as well as the use of electric power as industrial power or energy industrial enterprise departments commonly used and essential instrument. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. Digital Insulation Resistance Meter is composed of medium and large-scale integrated circuits, containing high-precision micro-current measurement system, digital boosting system. Only need to use a high voltage line and a signal line to connect the test piece can be measured. Measurement is carried out automatically and the results are displayed on a large screen and stored.
Rated output test voltage range 250 ~ 5000V, insulation resistance measurement range 0.01MΩ ~ 5.00TΩ.
