ZX119-3 insulation resistance meter calibration device, megger calibration device

The ZX119-3 insulation resistance meter calibration device is developed and produced in accordance with relevant documents such as JJG622-1997 Calibration Regulations for Insulation Resistance Meters, JJG1005-2005 Calibration Regulations for Electronic Insulation Resistance Meters, and JJG1072-2011 Calibration Regulations for DC High Voltage High Value Resistors. The instrument is designed with independent leakage shielding terminals and grounding terminals. It can not only be used to verify the standards of various types of imported and domestic analog insulation resistance meters, digital insulation resistance meters, and insulation resistance testers, but also can be used as a DC standard high-value resistor. It has a long technical life and mechanical life.
