The next generation of Megger's multifunction testers, the MF T1711-BS is an entry-level electrical installation tester best suited for those new to the electrical industry, or those looking for a simple tester that performs all basic tests. This product is the direct evolution of the highly popular Megger MFT1710.
Suitable for use in industrial, commercial and domestic fixed wire installations, the MFT1711-BS is designed for use in testing all low voltage electrical installations in accordance with BS7671.
Megger's multifunction testers are designed with both ease of use and durability in mind. Test activation buttons on either side of the unit make it simple to activate a test even in difficult conditions, while a large size LCD screen and colour-coded testing dials make it easy to select the exact testing parameters you need.
The MFT1711-BS will do every basic electrical test you need; it can test insulation, continuity, loop and RCD plus supply measurements with true RMS accuracy.
There are three models in the Megger MFT1700 series; the entry-level MFT1711, the mid-range MFT1721 and the advanced MFT1731.
This table outlines the difference between each product in the series.
