Megger MFT1731-OS Multifunction Tester - Onsite Bundle with Software Details
The complete package for professional electrical installers, this special onsite bundle package includes everything you'd get as standard with the Megger MFT1731 multifunction tester, plus additional accessories including Megger's Powersuite software and an earth spike kit to enable direct earth resistance testing.
Megger's MFT1731 is the most advanced model in Megger's multifunction tester series. With a huge range of testing functions, advanced safety features and fully downloadable memory (store up to 1000 results) it includes everything an electrical installer will need for testing low voltage installations in domestic, commercial and industrial properties.
With Megger's MFT1731 On-site package, you'll have everything you need for managing your test reports. Use this package to store/download results, download to PC, or even to allow multiple users to test different parts of the installation at the same time, then combine their results into one comprehensive testing report afterwards. You can even allow multiple users to complete the same certificate at different times, even if they're using different testers.
Every test you need can be performed with the MFT1731; this advanced test can perform insulation, continuity/resistance, loop, earth, RCD, voltage supply, leakage current and other measurements, ensuring you get fully comprehensive reports.
