FAQ's. Are infrared thermometers dangerous?. Infrared thermometers are not harmful, they do not emit radiation, only measure it like a digital camera. How accurate are infrared thermometers?. The majority of IR thermometers have a measurement error specification, which shows their best accuracy. The surface being measured can also affect accuracy. Reflective objects result in lower measurements than the actual temperature, whilst non-reflective surfaces give higher measurement. The emissivity of a surface is how effective it is at emitting energy as thermal radiation, as such some IR thermometers have adjustable emissivity settings. Distance to spot ratio is also essential in providing accurate temperature measurements, if an infrared thermometer is too close to its target area, heat can build up in the device. This can give false readings or damage the temperature sensors, therefore it is essential to always follow a manufacturers guidelines.
