Megger MFT1731 Installation Tester

Shipped as standard in a large soft carrying case, the Megger MFT1731 builds on the capabilities of the MFT1721 by adding support for three-pole ART earth resistance measurements, with a clamp option, and stakeless twin-clamp earth resistance measurements. This model also has internal storage for test results with wireless downloading to smartphones, tablets and other Bluetooth-equipped devices.

All of the multifunction installation testers in Megger’s new range incorporate the qualities that have made the previous MFT1700-series instruments so popular and successful. These include a straightforward user interface for fast easy operation, robust construction to withstand the knocks and tumbles of everyday use, comprehensive electrical protection, and an extensive range of safety features, including a CAT IV 300 V/CAT III 600 V safety rating in line with IEC 61010.
