Lowenergie Plug-in Energy Monitor Power Meter Review

The Lowenergie plug-in energy monitor is the best power meter and socket tester because it can help save you money on your electricity bills. UK based energy saving product experts Lowenergie have made it their business to help everyone track, monitor and understand how much power your devices are using, even when they’re “switched off”.

The monitor’s small enough to fit a single plug, but it’s still large enough to hold an easy-to-read LCD display. You can plug it into any standard socket, and it will tell you how many Watts it’s consuming in real time.

The internal memory allows you to record the kilowatt-hour usage over time, and you can even set how much each hour costs to give you an accurate idea of what you’re spending on each device. If you’re interested in tracking your energy hungry home appliances, this is the best power meter for you.

Martindale CP501 Classic Check Plug 240V Socket Tester Review

With over 90 years of electrical safety testing experience, Watford’s Martindale Electric produce a brilliant range of multimeters, test tools and PAT testing equipment. We got hold of their CP501 check plug and took it for a test drive.

The first thing you’ll notice is how simple this socket tester is. It’s probably one of the reasons why Martindale have sold over two million of these clever devices. All you have to do is plug it into any standard 240 Volt socket and hope that all the lights come on. If they don’t, there’s a fault.

It detects 28 fault conditions, all using three bright LEDs and a handy guide to pretty much anything that can go wrong with a 13 Amp socket. It’s small, lightweight and easy to throw into a toolbox for whenever you need it. It’s the best socket tester we’ve used so far.

Kewtech KEWCHECK103 Mains Wiring Socket Tester Review

UK based Kewtech are well-known for their quality testing equipment for professional electricians as well as keen DIYers. Their multifunction testers are used by professionals across the country, but we just wanted to try out the KEWCHECK103 Mains Wiring Socket Tester, one of their simpler bits of kit.

First off, it’s light and portable, as you’d expect from the best socket tester. It uses a three light system to clearly display faults in 13 Amp sockets on the live, neutral and earth wires, and translates the fault information onto the screen.

The feature that sets this apart as being the best socket tester for professionals has to be the audio warning feature. If the socket you’re testing is good, the Kewcheck plays a tone- if there’s an issue it warbles. This is handy if you’re testing a consumer unit or individual fuses on a circuit because you don’t need to see the socket tester to know there’s a fault.

Quille Habotest Socket Tester Mains Outlet Tester Review

When we were looking for the best socket tester available to the UK market, we came across the well rated Habotest HT106E, and decided to measure it up against the competition. It’s slightly larger than the competition, which might make it a bit more awkward, but it’s worth it for the extra functionality.

This device tests for up to seven wiring conditions and uses the familiar set of three LEDs to show up issues with the live, neutral and earth wires. What we like about this socket tester is that it displays real-time voltage to check for stability as well.

The last feature we were impressed to see on this device is the RCD tester. To check that your RCD breaker is working correctly, you can press the button and it will trip the RCD, as long as it’s working properly. It’s a useful feature to have if you need to do some home fault finding.
