Three lamps find wiring faults; they do not find a bad earth · review
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.
What the figures leave us with The readable one. A large screen turns a stoop-and-squint check into a glance.
A socket tester designed to be read from standing up.
Fast and safe checking of socket wiring, with indication of connection or wiring faults. An integrated RCD test at 30 mA on 230 V AC, allowing the important check that the protective device operates. A clear 2.0-inch LC display showing the connection state legibly.
Testing every socket in a house means twenty or thirty bend-downs. A lamp pattern has to be decoded against a printed legend at the same crouching height; a two-inch screen showing the state in words is read from standing. That is the difference between a job that gets done properly and one that gets sampled.
The earth. As with every socket tester here, a high-resistance earth lights the same indication as a sound one, and only a loop impedance test distinguishes them.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

Because sockets are at floor level. A tester read from standing height with a 2-inch screen is read; one with three small lamps and a printed legend is bent down to.
Testboy states it tests residual current devices at 30 mA on 230 V AC, allowing the essential check that the protective device actually operates.
Not in this listing. The GOMETY tester in this hub states CAT II 300 V.

Socket tester with RCD trip · plus a 12–1000 V contactless pen · auto power-off
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.
Best for: 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
