Releases a warble tone for fault. - Checks for the polarity of the mains supply., Checks RCDs with measured current. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01L4PODU2 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 38,003 in DIY & Tools ( See Top 100 in DIY & Tools ) 65 in Multi Testers | | Certification | ul | | Colour | Grey | | Customer Reviews | 4.7 4.7 out of 5 stars (850) | | Date First Available | 1 Jan. 2010 | | Included Components | 1 x Loopcheck 107 | | Item Package Quantity | 1 | | Item Weight | 80 g | | Item model number | Loopcheck 107 | | Manufacturer | Kewtech | | Material | Plastic | | Measurement Accuracy | 1 | | Number of Pieces | 1 | | Part Number | LOOPCHECK107 | | Power Source | AC | | Product Dimensions | 5.5 x 7.2 x 6.4 cm; 80 g | | Size | No Size | | Style | Single | ## Images ![Kewtech Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size - Image 1](https://m.media-amazon.com/images/I/71df+SJl5FL.jpg) ![Kewtech Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size - Image 2](https://m.media-amazon.com/images/I/41rGcY9k0GL.jpg) ![Kewtech Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size - Image 3](https://m.media-amazon.com/images/I/41EhY7oZSQL.jpg) ![Kewtech Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size - Image 4](https://m.media-amazon.com/images/I/41IvXgC54cL.jpg) ## Questions & Answers **Q: What is the difference of the 103 skt tester? Apart from 30 quid?** A: The 107 does a rough loop test ,green for less than 1.8 ohms ,and a mains reversed test.Also most usefully is the RCD test. It's great for turning the right circuit off on poorly labelled boards.If your regularly work on maintenance it worth every penny in time saved and annoyed customers . **Q: used this only a few times and now and suddenly the amber on the earth keeps flashing in every socket i try?** A: It may just be that the socket is old or the earth connections are loose. I’ve replaced the sockets that had amber light and now they’re fine. **Q: Does this tester ever need calibrated?** A: No. It should only be used to confirm polarity and earth continuity plus the correct operation of RCDs. For BS7671 testing a calibrated instrument should be used giving the trip time in milli-seconds. It should be checked periodically against a known source for future use. **Q: Is this more suited for a professional electrician?** A: This is a handy piece of kit to have in your tool box in my view whether you're a professional electrician or DIY - provided you know what your doing. It's a better tool than the ordinary plug in tester which only checks polarity and earth problems etc. This tool tests much more and although more expensive is well worth the money. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tester *by S***T on 19 January 2026* Excellent choice. Does what it says and is easy to use. ### ⭐⭐⭐⭐⭐ Kewtech 107 *by K***M on 21 April 2026* Excellent product which gives excellent readout info. This device has flagged up two issues that I was able to address and rectify. ### ⭐⭐⭐⭐⭐ Excellent Tester for the Price. Simple to Use. *by M***A on 1 July 2025* At £36.50 this was the cheapest tester I could find that included an Earth Loop Impedance check. Extremely simple to use: plug it in and turn the socket on. Green lights and continuous tone = good. Anything else bad - see enclosed leaflet. Won't trip the power unless you press the RCD test button (which is specifically to test tripping the RCD.) From another forum: less than 1.8 ohm loop impedance is considered good (green). 1.8 to 100 ohm. amber. More than 100 ohm red. ## Frequently Bought Together - Kewtech Loopcheck 107 LOOPCHECK107 Mains Socket Tester with Loop Check, Grey, No Size - Kewtech KEWCHECK R2 Socket Testing Adaptor - Test Without Removing Wall Socket - Kewtech KEWCHECK103 Mains Wiring Socket Tester --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/52373674-kewtech-loopcheck-107-loopcheck107-mains-socket-tester-with-loop-check](https://www.desertcart.ae/products/52373674-kewtech-loopcheck-107-loopcheck107-mains-socket-tester-with-loop-check) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-17*
