Kewtech KEWCHECK103 Mains Wiring Socket Tester

Really useful socket tester. It’s simple to use, gives clear results and makes checking sockets quick and easy. Compact enough to keep in a toolbox and feels well made. Great little tester!

Works well and the one I received was green and triangular not like the photo of a grey square one on amazon, apparently I now have the new 2026 model, which is nice. so I tested a socket in my living room and it showed a fault, when I opened the socket the live and neutral were reversed, it has been like that since the house was rewired in 1986 ! So I have now tested them all. Really useful tool, small and compact and the sound is loud but not too annoying. Happy !

I have one as my backup. I recently had to use it as my preferred choice, my ever faithful, Socket & See SOK32 decided to grow legs and vanish or should I say was borrowed on a permanent basis, as they do around other trades lads. I only have one gripe and that’s the audible tone is pretty pathetic just like many other brands including the big boy names so when using it to help find circuits on your own a loud one is a must hence why I HAD my SOK32. I would recommend this as it does what it’s supposed to and at 1/3rd the price of the SOK32 it’s a great price, however I will be purchasing another socket & see simply because I need something louder.

Even though the continuous beep noise that is rather loud and piercing, you definitely know that your wiring is safe. If there’s any problem you will get beeping and lights will show you where the problem lies. Tried on a test lead leaving earth disconnected and it showed the problem instantly. Very accurate. Well made, easy to use, and worth the money.

I consider myself fairly confident and competent when it comes to basic electrical DIY tasks (like replacing/checking sockets) but this absolutely provides added peace of mind to ensure they're being done safely - highly recommended!

Great bit of kit works as described all is good.

I love this little device. I’m not a professional electrician, just a home gamer so I don’t have bags full of testing equipment. This came in handy when one side of a twin socket started playing up, initially working intermittently and then failing completely. This showed a faulty connection and on examination ⚠️ (mains isolated first!!) ⚠️ it turned out the bus bar bridging the two sockets had burnt out (later traced back to a faulty kettle). New socket installed and tested. Didn’t work. 🫣 rather than panic I plugged this little tester in and found that the neutral wire had pulled out of the terminal while wrestling with the re-fitting of the new socket. Wiring sorted I plugged it back in and it worked fine. The audible beep (and lack thereof when no power is reaching it) was a good indication that I’d isolated the right circuit at the consumer unit. (If in doubt turn the whole supply off!). As a ray to use diagnostic tool for professional electricians and avid home gamers alike, this is invaluable to have in your tool bag. It’s a lot less intimidating for noobs than the rather dubious practice of poking multimeters or continuity testers into the plug terminals. We grow up being told NEVER to poke anything into plugs, and only those foolhardy enough to ignore this advice grow up to become electricians! Once you’ve used it for a specific job, you will then run around the house testing every socket, and when all sockets are checked, you will go door to door offering to check your neighbours’ sockets 😄
