It loads the circuit, which is why it does not lie to you · review
A 1000 V two-pole tester with a self-test function that checks the integrity of the instrument itself, in an IP65 body.
What the figures leave us with Buy it for the self-test and the sealing. The unpublished category is the one thing that should not be missing at this price.
A tester specified around the way testers fail.
An LED display indicating the voltage range between 12 and 1000 V. A self-test function, stated as increasing safety by verifying the integrity of the tool. A robust design certified to IP65 for dust and water resistance, stated for durability under difficult conditions.
A voltage tester that has stopped working looks exactly like a circuit that is dead. That is the entire hazard of the instrument, and it is why the discipline of proving on a known live source exists. A self-test does part of that job on demand, without needing a live source to hand — which in practice means it actually gets done.
It does not replace the discipline. Prove live, test, prove live again.
No category and no voltage rating in the listing, where the twelve-euro Kopp states CAT III. That gap is documented rather than excused: read the specification sheet in the box before the first use.
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

Bosch states it verifies the integrity of the tool. That addresses the scenario that makes a tester dangerous: one that has failed silently and now indicates nothing on a live circuit. It does not replace proving the tester on a known live source before and after the measurement that matters.
It is not stated. That is surprising on an instrument in this class and it is the same omission found across most of the electrical instruments on this site. The rating will be in the documentation supplied with the tool.
Dust-tight rather than dust-protected, and resistant to water jets rather than splashing. For a tester used outdoors or in a wet plant room, that is a real difference.

1–1000 V AC / 1200 V DC · True RMS · tested to DIN EN 61243-3, VDE 0682-401
The only tester here that names the standard it is approved to: DIN EN 61243-3 and VDE 0682-401:2015, with a 1–1000 V AC and 1200 V DC range and indication from 50 V even on flat batteries.
Best for: Photovoltaic, industrial and hybrid-vehicle work, where 1200 V DC is real and the approval matters.
CAT III stated · 8 LEDs from 6 to 400 V · thermal overload protection
A two-pole tester with an eight-step LED display from 6 to 400 V, thermal overload protection and screw-on contact sleeves for socket work.
Best for: Everyday domestic checking, at the price where a tester stops being an excuse not to have one.
CAT III 400 V · IP64 · 8 LEDs 6–400 V · green under 24 V, red from 50 V
A two-pole tester with a color-coded LED scale — green for extra-low voltage up to 24 V, red for dangerous voltage from 50 V — stated as CAT III 400 V and IP64.
Best for: Anyone who wants the safe-or-not judgment made by the instrument rather than by reading a number.
