Megger, a manufacturer and supplier of test equipment and measuring instruments for electrical power applications, offers a new series of insulation and continuity testers that conform to IEC1010-1 standards. Rated to CAT IV 600 V, the MIT400 series provides greater user safety when testing in higher voltage environments.
Megger’s industrial insulation testers offer a wide range of features making them ideal for use by utilities, industrial, and commercial electricians as well as maintenance and service/repair engineers. The testers are suitable for use in high-energy systems throughout the electrical, power, and telecommunications industries.
The MIT400 series, which includes the MIT400, MIT410, MIT415, MIT420, MIT430, and MIT40X, offers an exceptional measurement range from 20 GΩ to 200 GΩ and features adjustable insulation test voltages from 250 V to 1000 V and 50 V to 1000 V.
A special application instrument offers voltages from 10 V to 100 V in 1 V steps. Bluetooth wireless data transfer and test result storage are available in the top-of-the-range models.
For fast cable resistance measurements, these new industrial insulation testers are able to measure continuity at 200 mA or 20 mA down to 0.01 Ω. The testers take DC voltage measurements as well as TRMS measurements allowing for accurate data on noisy lines.
The MIT400 series combines both an analog arc and dual digital display readout. The dual digital display features a large main digital readout for good visibility of all main measurement results. Megger’s patented analog arc display is incorporated in the unit to replicate the response of a moving coil analog pointer.
Four of the six testers also feature a polarization index (PI) and dielectric absorption ratio (DAR) function in addition to adjustable continuity pass/fail limit alarms. A free calibration certificate is included with each unit. Each tester is sealed to IP54 providing a weatherproof case to lessen the chance of water ingress. A three-year warranty comes standard with each product.
