This latest series of multifunction installation tester adds one to the nomenclature and vastly to the value of these testers. The range of 3 instruments are expressly for testing low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations.
MFT1721 - The most popular of the range of 17th Edition testers offering all the benefits of the MFT1710, including auto RCD testing and adding phase rotation, 3-phase RCD testing and current measurement with the optional clamp.
This now adds an additional 100V insulation test range, true RMS voltage measurement, mV sensor input and Type B RCD testing
