Megohmmeter Model 5050 (Digital, Analog Bargraph, Backlight, Alarm, Timer, 500V, 1000V, 2500V, 5000V, Auto DAR/PI/DD)

Description: The Digital/Analog Megohmmeter Model 5050 is the latest design in 5000V insulation testers. Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR), Polarization Index (PI) and Dielectric Discharge (DD). The Model 5050 displays the test voltage, insulation resistance ad the leakage current during the test. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test. This meter is designed with the highest level of built-in safety features. The Model 5050 can be operated from an internal rechargeable battery system or from an AC line power.
