Hong Kong Hima AR907A+digital megohmmeter
Product details
Insulation resistance tester, commonly known as megohmmeter or high resistance meter, is widely used to measure the insulation resistance of generators, motors, power transformers, wiring, electrical appliances, and other electrical devices such as control, signal, communication, and power cables. They are often used in routine maintenance procedures to indicate changes in insulation resistance of motors over months or years. A significant change in insulation resistance may indicate potential faults. So, it is necessary to regularly calibrate the megohmmeter to ensure that the instrument itself does not change over time.
