The distance-to-spot ratio decides what you actually measured · review
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.
What the figures leave us with The usability choice: emissivity handled by material rather than by number. Fewer published specifications than anything cheaper here.
An instrument designed around the setting nobody adjusts.
A measuring range of −30 °C (-22 °F) to +500 °C (932 °F) for the surface temperature of everyday objects. Aim, press the trigger and read. More precise measurement by switching between three emissivity settings according to material. Bosch also lists sustainability features for this reference.
Emissivity is the single most important setting on an infrared thermometer and the one least often touched. A continuous scale from 0.1 to 1.0 assumes the owner knows the value for painted steel, and most do not. Three material-based presets make the correction a choice between things you can see rather than numbers you have to look up.
That is a genuine design decision, and it costs capability: no preset will match bare polished metal, which the adjustable thermometers here can be set for.
No distance-to-spot ratio and no accuracy. Both appear on thermometers costing half as much in this same hub, and both are the figures that let a reading be interpreted.

For the surfaces most people measure — walls, radiators, windows, appliances — yes, and they will actually be used. A continuous 0.1 to 1.0 adjustment is more capable and, in practice, is left at its default by most owners.
Not stated in this listing, where all four cheaper thermometers here publish 12:1. It is the specification that determines what area a reading covers, and its absence is a real gap.
None in this listing. Only the TempPro in this hub publishes a figure.

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.
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.
