Martindale ET4500 18th Edition Rechargeable Multifunction tester

The ET4000 and ET4500 testers carry out all the tests needed to verify the safety of electrical installations in domestic, commercial and industrial wiring installations in accordance with latest BS7671 18th Edition Wiring Regulations published July 2018.

The testers simplify 18th edition testing by having the latest fuse tables for Zs values built-in together with red and green LED indicators for instant pass/fail results.

Everything about the ET Series has been designed to save time and make testing easier, from the capability to display all results from an RCD autotest on one screen to the inclusion of useful Help menus at the press of a button. Even the soft carry case has been designed to enable testing without having to unpack and repack the instrument every time. On connection the testers carry out an automatic polarity and wiring check identifying potentially dangerous wiring faults in advance of any testing.

  • MFT 3 lead set RBG – MARTL3
  • MFT mains lead set RBG – MARTL207
  • Remote start probe – MARTL180
  • Soft carry case and strap
  • Quick start plus full user guide on CD
  • Calibration verification certificate
  • Low discharge rechargeable batteries
  • Mains charger



ET4500 Comes Additionally With:

  • ET-Link Software
  • USB Download Cable

Key Features:

  • Red and green LED indicators for instant pass/fail results
  • Built-in Zs loop impedance tables and help screens
  • Automatic polarity and wiring check on connection
  • Test and Go soft carry case, no need to unpack and repack
  • Auto RCD and ramp test with all results on one screen
  • TRMS voltage measurements and phase rotation on all models

  • Low discharge rechargeable batteries and mains charger



ET4000-4500-Screens



Fast, reliable high current and non-trip loop testing comes as standard together with a high level of input protection and a CAT IV safety rating . Both models include phase sequence indication and TRMS voltage measurement to cover every job and ensure voltage levels can reliably be measured in all applications.

Both models are supplied with a full range of accessories including Martindale test leads with clips and prods all terminated with industry standard 4mm plugs. The slimline Martindale remote start probe with test button is included as standard allowing one handed measurement in those areas that are hard to reach

Fast, reliable high current and non-trip loop testing comes as standard together with a high level of input protection and a CAT IV safety rating . Both models include phase sequence indication and True RMS voltage measurement, so you are well prepared to take on any job, be it industrial or working on a site where it’s difficult to make reliable voltage measurements due to harmonics and distorted mains supplies.

In addition the ET4500 can be used to carry out 3 wire earth testing and has on board memory to store and download all installation test results for documentation.

The ET4500 comes with ET-Link Windows software for easy uploading of client, location, distribution board and circuit information from a PC to the tester and downloading the results for printing reports or exporting for use in other applications. The optional ET-Link PRO enables auto filling, managing and printing of the latest certificates included in the software.

The new ET Series testers are supplied with low loss AA rechargeable batteries which can be easily recharged in the tester with the mains adaptor or using the optional in-car charger.

Both models are supplied with a full range of accessories including Martindale test leads with clips and prods all terminated with industry standard 4mm plugs.
