The distance-to-spot ratio decides what you actually measured · review
A −50 to 600 °C (-58 to 1112 °F) thermometer with a response under 500 ms, and an emissivity fixed at 0.95 — stated plainly, which makes clear what it can and cannot be pointed at.
What the figures leave us with Honest about its fixed 0.95, which is more than most. Buy it knowing it cannot measure bare metal.
A thermometer that names its limitation instead of hiding it.
An accurate reading in 0.5 seconds. A temperature range of −50 °C (-58 °F) to 600 °C (1112 °F), stated as suited to barbecues, machinery and vehicles, and explicitly not for people. A distance-to-spot ratio of 12:1, an emissivity of 0.95 fixed, and a response time under 500 ms, with switching between °C and °F. Two batteries supplied.
Most cheap infrared thermometers have a fixed emissivity and do not mention it. Printing “0.95 (fixed)” tells the buyer exactly which surfaces the instrument is honest about, and it is the reason this review can give a clear recommendation rather than a caveat.
A strip of matt insulating tape stuck to a shiny surface takes the temperature of that surface and radiates like matt tape — which is close to 0.95. Measuring the tape rather than the metal turns a fixed-emissivity thermometer into a usable one, and it is worth knowing whichever instrument you own.
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

Anything shiny. Bare aluminum, polished steel, copper pipe and foil all have emissivities far below 0.95, and a thermometer that assumes 0.95 will read them far too low. The fix without an adjustable instrument is a patch of matt tape or matt paint on the surface, measured instead of the metal.
It removes a setting that can be left wrong. A thermometer with adjustable emissivity set to 0.3 and forgotten is worse than one that is always 0.95 — but only if you know which you have.
Cooking surfaces, radiators, painted walls, plaster, plastic, wood, food — anything matt and non-metallic sits close enough to 0.95 for the fixed value to be right.

−30 to +500 °C (932 °F) · three emissivity settings by material
A thermometer that replaces a continuous emissivity dial with three presets chosen by material — a middle path between a fixed value and a number most people never set.
Best for: Household and building use by someone who will never set an emissivity number by hand.
12:1 · −50 to 610 °C (-58 to 1130 °F) · emissivity 0.1–1.0 · 500 ms reading
The widest temperature range in this hub at −50 to 610 °C (-58 to 1130 °F), with full emissivity adjustment and a stated 500 ms reading time.
Best for: Sweeping a surface for hot spots, where the 500 ms response makes a scan possible.
12:1 · −50 to 550 °C (-58 to 1022 °F) · ± 1.5% stated · 0.1 °C (32 °F) resolution · 500 ms
The only thermometer in this hub that publishes an accuracy figure — ± 1.5% — alongside a 0.1 °C (32 °F) resolution and a stated 20 cm (7.9 in) working distance for a 1.6 cm (0.6 in) spot.
Best for: Anyone who wants a published tolerance rather than a range and a ratio.
