Megaohmmeter PSI-2500

Megaohmmeter PSI-2500 is the best offer in its price category among megohmmeters with a test voltage of up to 2500 V. The device is designed to measure the insulation resistance of electrical circuits that are not energized and measure alternating voltage. After measuring for 1 minute, the device automatically calculates the absorption coefficient. The calibration interval is 2 years. The design of the device allows you to work at temperatures from -10 to +55 degrees. Power is supplied by 5 AA batteries.
