Digital insulation resistance tester, also known as megohmmeter, high-voltage insulation resistance meter, is used for insulation resistance testing.
This instrument has a shock-proof, dust-proof and moisture-proof structure, and is suitable for harsh working environments. It is a common and indispensable instrument 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 insulation resistance value of various insulating materials and transformers, motors, cables and electrical equipment, etc.
The digital insulation resistance meter consists of medium and large scale integrated circuits. The instrument has large output power and many output voltage levels (5 voltage levels).
Rated insulation test voltage range:100 ~2500V.
Insulation resistance measurement range:0.01MΩ~2000GΩ.
DC voltage measurement range: 0~1000V
AC voltage measurement range: 0~750V.
