Megohmmeters/Insulation Test

Megohmmeters & Insulation Resistance Testers


Transcat stocks insulation resistance testers that support cable analysis and production line testing. An insulation tester is an ohmmeter that measures the electrical resistance of insulating components. The tester outputs a high DC voltage to generate a current through and over the tested insulation. Readings indicate the amount of current escaping from the insulating material. Since meter resistance values can be displayed in megohms, devices are also called megohmmeters. Transcat honors megohmmeter leader, Megger, for its century of experience in testing insulation resistance by offering a full range of the brand’s instruments. In addition, we carry top testers from Fluke, AEMC, Extech and other top manufacturers.



Buy Calibrated Megohmmeters Only From Transcat


Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute. If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our Megohmmeter calibration services so that your instrument arrives ready to be put into use.


Simply add calibration to your order on the product page or checkout screen.



Choosing a Megohmmeter


Our high-accuracy Megohmmeters measure insulation resistance within various ranges and specified test voltages, with additional measurement functionality available. A single Megger model may measure insulation resistance, voltage, current, and capacitance in high-voltage electrical systems. Our insulation testing selection features hand-cranked general units, combination digital/analog instruments, and compact digital testers. We offer tools for electricians, technicians and engineers who need instruments for power utility, industrial, commercial, and telecommunications applications. When choosing a megohmmeter, consider scale and display type, measurement and test ranges, ease of operation, programmable run times and other factors.



The Best Insulation Testers


Megger’s new MIT525, MIT1025, and MIT1525 were designed with the customer in mind, and include a patented digital/analog display. Or rely on the AEMC 1060’s dual display and fully automatic report generation. Browse our Fluke 1555 insulation testers that provide digital testing up to 10 kV, making them ideal for a wide range of high voltage equipment including switchgear, generators and cables. We also stock AEMC models, which offer automatic DAR, PI and Capacitance functionality.
