I use my Outest GM320 infrared thermometer already for a couple of years now, and I'm quite happy with it.
It gives you a fast relative correct reading.
We unbox and test this very thourough today.
Remember after the video, I added a whole piece where it fell apart and failed miserably.

What is emissivity and why is it important? (FAQ - Thermal)
All objects at temperatures above absolute zero emit thermal radiation. However, for any particular wavelength and temperature the amount of thermal radiation emitted depends on the emissivity of the object's surface. Emissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a blackbody (a perfect emitter) at the same temperature and wavelength and under the same viewing conditions. It is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter). The emissivity of a surface depends not only on the material but also on the nature of the surface. For example, a clean and polished metal surface will have a low emissivity, whereas a roughened and oxidised metal surface will have a high emissivity. The emissivity also depends on the temperature of the surface as well as wavelength and angle.
