MTS-5K Insulation Resistance Tester, also known as megohmmeter, high voltage megohmmeter, high voltage insulation resistance tester, etc. Also known as , it is mainly used for insulation testing in the laboratory or on site. The instrument has a gray and white backlit display, a large LCD display with data storage, data access and other functions. At the same time, it automatically calculates the absorption rate and polarization index, and automatically stores data for 15 seconds, 30 seconds, 1 minute and 10 minutes. High resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. In addition, it has a structure that is resistant to impact, dust and moisture.
It is a common and indispensable tool for telecommunications, electric power, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electric power as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and insulation resistance of transformers, motors, cables and electrical equipment.
It consists of medium and large scale integrated circuits, including digital insulation resistance meter, high precision micro current measurement system, digital boost system and automatic discharge circuit. To measure the DUT, you only need to connect it with a high voltage line and a signal line. The measurement is done automatically, the results are displayed on the big screen and the results are stored. The rated output test voltage range is 250V~5000V, and the insulation resistance measurement range is 0.01MΩ~5.00TΩ. The DC voltage measuring range is 0V~1000V DC, and the AC voltage measuring range is 0V~750V AC.
