Latest electrical installation testers

The new ET4000 and ET4500 testers simplify 17th Edition testing by featuring the latest third amendment fuse tables, built-in together with red and green LED indicators, for instant pass/fail confirmation of all main test functions.

On connection the new testers also carry out an automatic polarity and wiring check, identifying potentially dangerous wiring faults in advance of any testing.

They feature auto RCD functions which can cycle through all the required tests and clearly display all four sets of results in one go and on one screen, reducing errors and speeding up the job. This is useful with the increasing use of RCDs following the changes in amendment 3.

The new series of testers feature a high level of input protection and a CAT IV safety rating, ensuring a high level of safety and reliability.

Two of the very few testers on the market which use True RMS (TRMS) voltage measurement, the ET4000 and ET4500 ensure that the supply voltage can always be measured accurately and is within the Cmim limits defined in amendment 3.  Both models also include phase sequence indication.

The ET4500 tester can also be used to carry out 3 wire earth testing and has onboard memory to store and download all installation test results for documentation, making it future proof for all potential applications.  The ET4500 is supplied with low loss AA rechargeable batteries which can be easily recharged on site with a mains adapter or optional in car charger.

Both the ET4000 and ET4500 multifunctional testers come complete in a soft 'Test and Go' carry case, allowing leads to be connected and testing to be carried out without having to remove the tester from the case saving time and trouble unpacking and repacking on-site

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 slim line Martindale remote start probe with test button is included as standard, allowing one handed measurement, in those areas that are hard to reach.
