The distance-to-spot ratio decides what you actually measured · review
A 12:1 infrared thermometer covering −50 to 590 °C (-58 to 1094 °F), with emissivity adjustable across the full 0.10 to 1.00 range — the setting that decides whether a reading on shiny metal means anything.
What the figures leave us with Full emissivity adjustment for seventeen euros. That is the specification that separates a useful IR thermometer from a toy.
The cheapest thermometer here with the setting that actually matters.
A distance-to-spot ratio of 12:1, stated as allowing measurement from a safe distance. Fast non-contact measurement of the flat surface temperature of objects from −50 °C (-58 °F) to 590 °C (1094 °F). An adjustable emissivity preset from 0.10 to 1.00.
Two thermometers pointed at the same shiny pipe will disagree, and neither is broken. Infrared measurement infers temperature from radiated energy, and how much a surface radiates depends on what it is. A dull painted wall behaves almost like a perfect emitter; a polished stainless pipe radiates very little and reflects the room instead.
A thermometer locked at 0.95 is calibrated for the wall and wrong on the pipe, by tens of degrees. Adjustment is the fix, and only three of the five thermometers in this hub offer it fully.
At 12:1 the instrument averages everything inside the spot. Aiming at a 2 cm (0.8 in) terminal from a meter away measures the terminal plus a great deal of the enclosure around it, and reports a temperature that belongs to neither. Get closer, or accept the average.

Every surface radiates a fraction of the energy a perfect emitter would. Matt paint is about 0.95; polished metal can be below 0.1, and it reflects its surroundings instead. A thermometer fixed at 0.95 pointed at bright metal reads badly wrong. Wintact states adjustment from 0.10 to 1.00.
At twelve units of distance the measured spot is one unit across — so at 1.2 m (4 ft) the reading is the average over roughly a 10 cm (3.9 in) circle. Anything smaller than that circle is diluted by whatever surrounds it.
No. These instruments measure surfaces. Devices intended for body temperature are a separate, regulated category and outside what this site covers.

−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.
