Megger Calibration & Repair
Authorized Service Center

“Megger” has become a generic trademark for most insulation testers as well as other units out in the field. But the “Megger” trademark has been held by its company for decades, a company that continues to grow and produce reliable products. And now, JM Test is an Authorized Service Center for Megger, one of a select few in the United States. JM is now able to service another group of stalwart products and provide equally reliable services for many instruments.
