Insulation Resistance Meter MIR-202
MIR-202 is a digital insulation resistance meter, also known as Mega ohm meter, high voltage insulation resistance tester, and is widely used for insulation resistance test. This instrument has the functions of data storage, data access, alarm, automatic shutdown and so on. At the same time, it also has the function of measuring the AC voltage absorption ratio and the polarization index of the DC voltage. MIR-202 is widely used as an indispensable instrument in electricity engineering, post and telecommunications, communications, mechanical and electrical installation and maintenance, etc. The device is suitable for measuring the resistance value of various insulating materials and insulation resistance of transformers, electro motors, cable insulation and electrical equipment.
