A pen that says nothing is not the same as a circuit that is dead · review
A trade detector covering 90 to 1000 V AC, stated for locating live conductors, cable breaks, blown fuses and defective components.
What the figures leave us with A plain, well-scoped trade detector. Nothing adjustable, nothing rated on the page, and a clear list of what it is for.
A detector that says precisely which jobs it is for.
Time-saving voltage checking by non-contact measurement. A wide range of 90 to 1000 V AC. Stated uses: detecting and locating live conductors, cable interruptions and breaks, blown fuses and defective components. Single-pole operation.
Most pens describe a range and stop. Listing the faults the tool is meant to find is more useful, because it tells you the intended technique: this is a tool for following a circuit until the signal changes, not just for checking whether a socket is live.
Nothing under 90 V registers. On a domestic or commercial mains job that is a feature — no false alarms from data and control wiring. On anything with extra-low-voltage circuits, it is a blind spot, and the 12 V pens in this hub cover that ground instead.
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

It ignores everything below mains voltage, which makes it quieter around control and signal wiring. It also means it will not find a 24 V or 48 V circuit at all.
By following the conductor: voltage present on one side of the fuse holder and absent on the other localizes the break. Wiha lists this among the stated uses.
Not in this listing. The two PeakTech pens in this hub do.

A plain, well-scoped trade detector. Nothing adjustable, nothing rated on the page, and a clear list of what it is for.
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.

A trade pocket detector for mains work, where nothing below 90 V is in scope.
Amazon reports what buyers took in the month before this page was last checked: at least 50.
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.
90–1000 V AC · flat tip · industrial reference
Fluke's industrial detector, 90 to 1000 V AC with a flat tip. The listing states almost nothing beyond the range and the form.
Best for: A workshop standardized on Fluke, where the catalog reference is worth more than the listing.
≈ $36
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
