The test voltage must match the circuit, not the other way round · review
A combined insulation tester and digital multimeter with 500 V and 1000 V test voltages and a 600 MΩ range, at the top of this hub by a factor of four.
What the figures leave us with Two instruments in one, behind a listing of three lines. The specifications live in the documentation, not on the page.
The most expensive instrument on this site, and one of the shortest listings.
Insulation testing at 500 V and 1000 V, with a range to 600 MΩ. Equipped with functions to protect the user. Additional tools or attachments included. Compact storage.
An insulation tester alone is a single-purpose instrument that spends most of its life in a case. Combined with a multimeter it becomes the instrument that is already in your hand when the insulation question comes up — which is the argument for the format, and it is a real one for anyone doing installation work daily.
No category rating, no accuracy figures, no continuity range. Fluke publishes full technical data elsewhere; what is on this page is less than the PeakTech at a fifth of the price offers. That is a statement about the listing, not about the instrument.

Because the two measurements happen in the same visit. An installation check needs voltage, continuity and insulation, and a combined instrument means one tool, one set of leads and no swapping mid-job.
It is a lower ceiling than the PeakTech's 4000 MΩ or the Voltcraft's 20 GΩ. For pass-or-fail testing against a minimum requirement it is ample; for tracking a slow degradation over years, a higher ceiling gives you more to watch.
The test voltages, the range, that it has user protection functions, and that additional tools or attachments are included. No category rating appears in the listing.

Two instruments in one, behind a listing of three lines. The specifications live in the documentation, not on the page.
A reference exists on these Amazon stores: France, Germany, Italy, Spain, United Kingdom, United States. Listed is not the same as in stock — availability changes daily.

Carrying one instrument instead of two, in a trade where that trade-off is worth the price.

Insulation resistance · multiple ranges · manual selection · backlit LCD
The entry point into insulation testing: a megohmmeter with several selectable ranges, manual measurement modes and a large backlit display.
Best for: Learning what an insulation test looks like, on equipment that is disconnected and safe to experiment on.
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.
50 / 100 / 250 / 500 / 1000 V · insulation to 20 GΩ · resistance 0.01 Ω–20 kΩ
Five test voltages from 50 to 1000 V and an insulation range reaching 20 GΩ — five times the ceiling of the PeakTech — with low-resistance measurement from 0.01 Ω.
Best for: Testing across a wide span of equipment, from electronics at 50 V to fixed wiring at 1000 V.
