The Megger MFT1721 builds on the MFT1711 with added functionality for contractors and testing engineers who need more from their multifunction tester. It retains the full suite of installation tests — insulation resistance, continuity, loop impedance, and RCD testing — while adding features that make it better suited to larger or more complex installations.
The MFT1721 includes Bluetooth connectivity for wireless data download to the Megger PowerSuite or compatible reporting software, cutting the admin time between testing on site and producing your electrical installation condition reports. The instrument also supports a wider range of RCD test types and offers improved memory for storing test results in the field. If you're running a team, managing multiple sites, or simply want to streamline your reporting workflow, the MFT1721 is worth the step up.
