Cuthbertson Laird are now offering a kit comprising of a multifunction installation tester, the highly popular Megger MFT1721, plus the award-winning, new earth leakage clamp from Megger, the DCM305E. The total list price is £1449. Buy today for only £899 + VAT.


Designed from the outset with safety and convenience in mind, the MFT1721 tester provides comprehensive and easily accessed facilities for testing electrical installations in line with the 17th Edition of the IET Wiring Regulations. The MFT1721s are extensively protected against damage if they are accidentally connected to a live supply when a dead circuit test is selected, and this protection is effective even if the test has been locked on.

The Megger DCM305E is designed to check earth leakage currents; however the upper range enables TRMS AC current measurements of up to 100 A. TRMS meters can measure both pure, undistorted, sinusoidal AC waveforms and non-sinusoidal AC waveforms which can contain pulse trains, triangles, spikes and other ragged waves.
