Megaohmmeter PSI-2530

Megaohmmeter PSI-2530 is designed to measure the insulation resistance of electrical circuits that are not energized, and measure alternating voltage up to 700 V. The presence of a magnetic holder allows you to fix the device to any metal surface.

At the end of a series of measurements, the results from the memory of the device can be transferred to a computer via wireless communication for further processing and entering into the protocol. In gas services, it is also used to measure the transient electrical resistance of the insulating coating of pipelines laid in the ground, as well as new pipes, GOST 9.602-2005 is allowed.

Increased resistance measurement range up to 1 TΩ. The device also allows you to carry out work on testing surge suppressors and arresters, which are widely used in industrial electrical installations and lightning protection elements.
