Megger MFT1731 Multifunction Tester

The Megger MFT1731 18th Edition Tester is a fully loaded tester, designed for those who require a tester that performs day in day out and is capable of covering every eventuality you might come across when testing.

Its packs the great features of the MFT1711 and MFT1721 such as EN 61010 CAT IV safety rated, 3 and 2-wire non trip loop testing with resistance and fault current display, frequency measurement and the largest, brightest and clearest display on the market. Not forgetting it is still as easy to use every day with ‘LOCK’ and ‘TEST’ buttons on either side of the instrument, ideal for both left and right handed users.

The 1731 Multifunction Tester is still suitable for beginners and advanced users alike, futureproofing with features such as Type B RCD Testing and TRMS.
So what does the Megger MFT1731 add that makes it so complete? The MFT1731 has enabled additional earth electrode testing options such as 3-pole ART electrode testing and stakeless electrode testing. The clamps are optional accessories. Also included are a set or rechargeable batteries (charger included) A single charge can provide up to a month’s battery life dependant on use!

The on board memory makes storing up to 1,000 results as easy as possible, plus there is always the option to download your result via Bluetooth to your PC using Megger Download Manager (supplied) As an option, the MFT1731 is available complete with PowerSuite® Lite software as the MFT1731 On-Site.
Every Megger Multifunction Tester is built to last, it won’t go bang when dropped, bounced, left out in the rain, connected across phases or even locked on and connected to a live circuit! This tough reputation is topped off with a Megger 3 year warranty for complete peace of mind.
