The distance-to-spot ratio decides what you actually measured · review
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.
What the figures leave us with The only published tolerance here, paired with an unstated emissivity setting. An unusual trade.
One thermometer in this hub tells you how close it gets.
An integrated laser pointer for aiming at the measuring point. A 12:1 distance-to-spot ratio, with a recommended distance of 20 cm (7.9 in) giving a measuring area of about 1.6 cm (0.6 in). Surface temperature measurement from −50 °C (-58 °F) to 550 °C (1022 °F) with an accuracy of ± 1.5%. A result in 500 ms with a resolution of 0.1 °C (32 °F).
“12:1” requires arithmetic before it means anything. “20 cm (7.9 in) gives a 1.6 cm (0.6 in) spot” is the same specification expressed as an instruction, and it removes the most common misuse of these instruments — standing back and measuring an average of everything around the target.
Emissivity. Nothing in the listing states whether it can be set. If it is fixed, every reading on bare metal is suspect; if it is adjustable, this is the best-specified thermometer in the hub. That question is answered by the manual, not by this page.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

It is proportional: at 100 °C (212 °F) it is ± 1.5 °C (35 °F), at 500 °C (932 °F) it is ± 7.5 °C (46 °F). That is the normal form for an infrared thermometer and it is more informative than the fixed figures quoted for contact instruments.
Because a distance-to-spot ratio is abstract. TempPro states 20 cm (7.9 in) gives a measuring area of about 1.6 cm (0.6 in), which is directly usable: it tells you how close to stand to measure a given target.
The listing does not say. The Wintact and Etekcity in this hub both state adjustment from 0.1 to 1.0, and the KETOTEK states a fixed 0.95. This one is silent, which for a measurement on metal is a real unknown.

Amazon reports what buyers took in the month before this page was last checked: at least 200.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

−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 600 °C (-58 to 1112 °F) · emissivity FIXED at 0.95 · under 500 ms
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.
Best for: Painted, plastered, plastic and organic surfaces — everything that is genuinely close to 0.95.
