A pen that says nothing is not the same as a circuit that is dead · review
Fluke's industrial detector, 90 to 1000 V AC with a flat tip. The listing states almost nothing beyond the range and the form.
What the figures leave us with A known instrument behind an almost empty listing. Buy it for the catalog, not for the page.
Three published lines from the brand people buy for its specifications.
Ninety to 1000 V. A flat tip. Additional tools or attachments included.
There is no category rating, no description of how it indicates, no sensitivity behavior and no ingress rating. That is not evidence about the instrument — Fluke publishes full data elsewhere — but it is what a buyer can see before ordering, and on this page it is less than the fifteen-euro PeakTech offers.
A pointed detector has to be held at an angle against a screw head or a busbar, and the sensed field changes with that angle. A flat tip lands the same way every time, which makes the comparison between two points meaningful.
It detects. It does not confirm absence of voltage. Prove any circuit you intend to work on with a two-pole tester, following the manufacturer instructions and the rules that apply where you live.

At $36, it is the 3 cheapest of the 3 models in this category published here.
The range, 90 to 1000 V, a flat tip, and that additional tools or attachments are included. That is the extent of it. We do not describe alert behavior or a category that is not stated.
It presents a flat face to a flat surface — a terminal screw, a busbar, a socket contact — instead of a point that has to be held at an angle. It makes the reading position repeatable.
Not on published specification, where the PeakTech states its category and three alert channels. On brand consistency within a toolkit, that is a judgment about your workshop rather than about the instrument.

A known instrument behind an almost empty listing. Buy it for the catalog, not for the page.
Same category, nearby prices, between measuring instruments. What remains is the specifications every one publishes — half empty, a column is no use.

| Fluke VoltAlert 2AC, 90–1000 V | $36 | 90–1000 V AC |

A workshop standardized on Fluke, where the catalog reference is worth more than the listing.
Amazon reports what buyers took in the month before this page was last checked: at least 1,000.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for measuring instruments and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
12–1000 V AC · auto and manual modes · stepless sensitivity · 8 LEDs in 3 colors
A detector with continuously adjustable sensitivity and an eight-LED, three-color strength display, so field strength is read as a scale rather than as a yes or no.
Best for: Picking one live conductor out of several, where a single-threshold pen lights up on all of them.
≈ $16
12–1000 V AC · CAT III 600 V stated · LED indication
A 12 to 1000 V AC contactless pen stating CAT III 600 V, with LED indication and an instruction to test the pen before each use.
Best for: A pocket first check, always followed by a two-pole tester before any work.
≈ $10
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.
