Three lamps find wiring faults; they do not find a bad earth · review
A two-piece kit: a socket tester with RCD trip function and a separate non-contact voltage pen covering 12 to 1000 V, with automatic power-off after three minutes.
What the figures leave us with Two useful tools, neither of them the best of its kind here. A reasonable start, not a considered pair.
Two instruments, one box, and less published about each than about their standalone equivalents.
A non-contact AC voltage pen detector with sensitivity ranges from 12 V to 1000 V and from 48 V to 1000 V, stated as usable on circuit breakers, light fittings, switches, sockets and wires. A socket tester for correct wiring and RCD trip function. Automatic switch-off after three minutes without operation.
The two questions an electrical check asks — is this socket wired correctly, and is this cable live — need two different tools, and one is useless for the other’s job. Buying both at once means neither gets postponed.
Neither half publishes a measurement category, where the individually sold instruments in this hub do. If you are buying one tool at a time, the GOMETY socket tester and the PeakTech pen each tell you more about themselves.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.
Read from Keepa on the day this page was last revised; stock and price both move without notice.

For a first purchase, yes — the socket tester and the pen answer different questions and most people need both. Bought separately, each of the individual instruments in this hub publishes more about itself than either half of this kit does.
The socket tester only works where there is a socket. The pen checks cables, switches, light fittings and breakers, which is most of an installation.
No category is stated for either. The GOMETY socket tester in this hub states CAT II 300 V, and both PeakTech pens state a category.

Equipping someone from nothing, where owning both tools matters more than owning the better one of each.

Battery-free · Schuko sockets · trips a 30 mA RCD from a test button
A battery-free socket tester for Schuko outlets that trips a 30 mA RCD directly from its test button — nothing to go flat, nothing to forget.
Best for: The tester that lives in the bag for a year and works when you finally reach for it.
2.0-inch LCD · RCD test at 30 mA / 230 V AC · connection and wiring faults
A trade socket tester with a 2.0-inch LCD reporting the connection state, and an integrated RCD test at 30 mA on 230 V AC.
Best for: Checking many sockets in sequence, where a readable screen beats decoding a lamp pattern each time.
CAT II 300 V stated · six fault types · six LEDs · one-button RCD test
A socket tester stating CAT II 300 V — the only socket tester here that publishes a category — with six LED indications and a one-button RCD trip test.
Best for: The socket tester to buy if you want to know where the instrument is rated to be used.
