Testing Equipment

Pocket testers from Knightsbridge for checking UK three-pin sockets and live circuits before and after work. The range covers a plug-in socket tester, an IP64 outdoor-rated two-pole voltage tester with LED and LCD display, and a non-contact pen reading 80 to 1000V AC. Handy kit for spotting faults quickly. Fixed wiring work is best left to a qualified electrician.

Socket and Voltage Testers

Pocket testers earn their place by letting you check sockets and live circuits quickly, both before work starts and once it is done. Our range covers a plug-in socket tester for UK three-pin outlets and voltage testers for confirming whether a circuit is live, giving you a fast read without reaching for larger gear. They suit anyone who wants to spot an obvious fault or confirm a circuit is dead before going further, though fixed wiring work is best left to a qualified electrician.

The socket tester plugs straight into a three-pin outlet and checks the wiring at a glance, flagging common faults so you know whether the socket is safe to use. Alongside it sits a two-pole voltage tester with an IP64 rating for outdoor and damp use, fitted with both LED and LCD display so you can read the result by light or figure. Its two probes touch across the points you are testing to confirm whether voltage is present.

The range also includes a non-contact voltage tester in pen form, reading 80 to 1000V AC, that senses a live conductor without you having to touch bare metal. Holding it near a cable or terminal gives a quick indication of whether the circuit is live, which is handy as a first check before you work any further. The pen format drops into a pocket or toolbag and is easy to reach for on the spot.

Pick the tester that matches the check you need, from a socket read to a non-contact live indication, and use it as a first step rather than a substitute for proper safe-isolation. Free UK delivery over £99, with worldwide shipping available.

Frequently Asked Questions

What does the socket tester check?
The plug-in socket tester goes into a UK three-pin outlet and checks the wiring at a glance, flagging common faults so you can see whether the socket is safe to use. It gives a quick read without needing larger test gear.

What is a non-contact voltage tester?
It is a pen-form tester, reading 80 to 1000V AC, that senses a live conductor without touching bare metal. Held near a cable or terminal, it gives a fast indication of whether the circuit is live as a first check.

Can the two-pole tester be used outdoors?
The two-pole voltage tester carries an IP64 rating, suiting outdoor and damp conditions, and has both an LED and an LCD display so you can read the result by light or figure. Its two probes touch across the points being tested.

Are these testers suitable for DIY use?
They are handy for spotting faults quickly and confirming whether a circuit is live, which suits a range of users. Fixed wiring work itself is best left to a qualified electrician, and a tester is a first check rather than a substitute for safe isolation.

What is the difference between contact and non-contact testing?
A two-pole tester touches probes across the points you are checking to confirm voltage, while a non-contact pen senses a live conductor from nearby without contact. The pen suits a fast first check, with the two-pole giving a direct reading across the terminals.
