AEMC 5050 2130.20 5000V Digital-Analog Megohmmeter

The AEMC 5050 5000V Digital Analog Megohmmeter is the latest most innovative design in 5000 Volt insulation testers.

The 5050 includes automatic presentation and calculation of the Dielectric Discharge (DD), Polarization Index (PI), and Dielectric Absorption Ratio (DAR). The 5050 displays leakage current, insulation resistance, and test voltage during the test. Capacitance of the discharge and sample voltage at the test leads is displayed when the test is finished, and is designed with the highest level of safety features. The 5050 can be operated from an AC line power or from an internal rechargeable battery system.
