Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size

The first socket I plugged it into was a new double socket, which was less than a year old. As expected all was good, I then went around the house and found (so far) that all sockets but one, tested perfectly. The one that didn't showed a 'Check' light on the Earth Loop test. That's the socket which is nearest the cooker and probably is a bit gunky. I'll change it in due course, even though the socket is not used for anything.Most four way block extension leads provided the 'Check' light on the earth test, interestingly newer extension leads and ones that I have recently serviced all tested as 'perfect'.I consider this to be an excellent addition to my tools and once life reverts to normal after the covid pandemic and I'm travelling on business again, this will go with me everywhere before I plug laptops etc in. i.e. a great safety check device in hotels and B&B's too.

Living in a house that’s over 100 years old, the wiring is very ‘suspect’ and we’ve been having annoying trips on one of the socket circuits for a few years now. Having replaced a few of the older sockets, this had improved things a little, but having subscribed to a few electricians YouTube channels, I later discovered that the earth wire is meant to be sleeved, and the few sockets I’ve replaced never had any. Also few had grommets in the back boxes. But decided to buy this socket tester as I know RCD trips can be caused by earth leakage. I decided to just try a random socket rather than one I suspect may have issues and to my surprise it was showing that the earth loop impedance needs looking at. This socket is quite old, so I will replace this at some point and may discover some poor installation. I’m not an electrician, but did study electronics servicing and was a car audio technician for a few years and have the sense to not take a chance with anything live. But this socket tester at least can do a safe and quick insight into potential dodgy sockets and I can point this out if an electrician is needed. But having seen various electricians use these for quickly identifying various circuits when doing an EICR, I’mconfident that even the professionals would agree this is an excellent choice for the money.

Works well. Helped me identify the washing machine as the cause of the RCD tripping when performing the loop test. Saved me an electrician callout.

It's save your time for faultfinding

The fist one I had stopped working after a being used about 20 times. I purchest a. Couple of them since and have given all but one of them away to people who would find them useful. As they test earth loop impedance from a 13 amp socket back to the consumer unit. I think it shows an error if it is greater than 1.5 ohms. Although I could not see that value mentioned in the instructions. Essential if you have the use of a mains pickup in a caravan or tent. Other test sockets generally do not provide this facility. If the earth impedance is higher, it could be dangerous. The metal case of a faulty appliance could experience a high voltage on its case without passing enough current to blow the fuse in the plug top on the appliance. Help!!!.

This should be a must-have item for every electrician!A bit slow for me, I would recommend to the product engineer to speed up the test. This is because measurement procedure has two steps. After connection in the first wiring measurement the result immediately knows and it keeps signalling for 2-3 secs and just after that start the second measurement for earth-loop impedance. While this second measurement start only if the first was successful, my recommendation is to reduce the first measure time only if it was good and if this 2-3 secs is not required for the correct measurement, of course if something is wrong than it should keep it signalling continuously.Anyway absolutely recommended stuff, I love it and not least very easy to use for a not trained people as well. Everything that you need to know, if anything else appear on display that all green and continuous sound then something wrong and must be check that socket outlet and/or wiring by a qualified electrician. This means a housewife can use it and keep it safe their family.P.S.: I would recommend to implement other type of socket to be able to use anywhere in the world.Thank you guys!

Good add on to my tool bag as a handyman

I'm pleased I bought this product after reading reviews for this and other similar mains socket testing products. It does several tests and clear indication of problems very quickly using the LED lights and beeps. The right-hand earth-loop testing button is very useful for testing sockets further away from the main distribution board, e.g. I have 3 outbuildings/sheds in the garden which are progressively further away from the house, and the Kewtech gave confidence that any earth problems were being handled by the RCD at the main board. The left button is a capacitance pad (it doesn't click/depress), it relies on your finger simply touching the button to show that low earth connection is detected and working. Very good device.
