The category and the voltage, printed together
Across ten electrical instruments on this site, two listings publish a complete measurement category. PeakTech wrote both.
Safety specifications. The P 1094 two-pole tester states CAT III 400 V AC/DC and IP54; the P 1030 detector states CAT III 1000 V; the P 2695 insulation tester states CAT III 1000 V and its four test voltages. Fluke and BENNING listings on this same site state none of those.
Presentation and availability. Several PeakTech references here are absent from the British or American stores, and the listings are terse — specifications without much explanation of what they mean.
The P 2695 insulation tester, for publishing all four of its test voltages. That is the specification an insulation tester is defined by, and it is the one most listings in that hub leave out.
50–1000 V AC · CAT III 1000 V stated · LED, buzzer and vibration
A 50 to 1000 V pen stating CAT III 1000 V, alerting by LED, buzzer and vibration, and usable for tracing a break in a wire.
Best for: Tracing cables and identifying the live conductor in noisy or poorly lit conditions.
CAT III 400 V AC/DC · IP54 · battery-free · audible warning from 50 V
A battery-free two-pole tester stating CAT III 400 V AC/DC and IP54, with an LED display and an audible warning above 50 V.
Best for: Domestic and light commercial installation work, with the rating printed where you can read it.
125 / 250 / 500 / 1000 V test · 0–4000 MΩ · CAT III 1000 V · dual display
Four selectable test voltages from 125 to 1000 V, insulation measurement to 4000 MΩ, continuity, AC and DC voltage — and a stated CAT III 1000 V rating.
Best for: Installation work where the test voltage has to match the circuit and the category has to be known.
Transmitter plus receiver · up to 2 m (7 ft) reception depth · 7 channels · live and dead cables
Not a wall scanner but a cable tracer: a transmitter injects a signal into a conductor and a receiver follows it, to a stated depth of 2 m (7 ft), on live or dead cables.
Best for: Following one specific cable through a building, which no wall scanner can do at all.
The instrument-grade format: 6.3 × 32 mm (0.25 × 1.26 in) at a rated 690 V, super fast-acting, which is what a properly specified meter current input takes.
Best for: The meter whose manual specifies exactly this — and it should be checked, not assumed.
A plain replacement pair for any meter with 4 mm (0.16 in) sockets, with insulated angled plugs and 18 mm (0.71 in) tips — and no published category rating, unlike the rated American sets on this shelf.
Best for: Replacing the leads that came with a meter, when the insulation has started to crack.
