SKU: 222222

Model: AEMC 6550

Part Number: 2130.31

Ordering Number: 222222


The Megohmmeter Model 6550 is a high-end portable measuring instrument intended for the measurement of a wide variety of electrical insulation resistance values on cables and devices operating at high voltage. It is the only fully automated 10,000V graphical insulation tester. The True Megohmmeter® Model 6550 is packaged in a rugged case that is IP54 when closed. Test results and configuration information are displayed on a graphical LCD screen, and are exportable via DataView®(provided). This megohmmeter can operate on battery or AC power.

The Model 6550 also offers the ability to program up to three step voltage profiles (from 40 to 10,000V), each containing up to ten steps. There are also ramp profiles and three programmable test voltages in addition to the standard fixed voltages of 500, 1000, 2500, 5000 and 10,000V.
