Infrared Thermometers
The Infrared Thermometers category covers non-contact surface temperature measurement devices that detect thermal radiation from the target and convert it to a digital reading, used in industrial maintenance, electrical equipment inspection and process monitoring. Models vary in temperature range, accuracy, distance-to-spot ratio and emissivity configuration. These instruments are not equivalent to thermal imaging cameras and do not measure internal core temperature. Specifications vary across models.

About this category
Infrared thermometers are non-contact temperature measurement tools that detect thermal radiation (infrared radiation) emitted from the target surface and convert it to a temperature reading shown on an electronic display. These devices measure surface temperature only and do not measure the internal core temperature of objects. Models differ in documented temperature range, documented accuracy and resolution; these three characteristics must be distinguished because a wide range does not imply higher accuracy. Many models include a laser pointer to indicate the measurement location, but the laser pointer is not the temperature sensor itself; it is only an optical aiming aid. The distance-to-spot ratio varies between models and defines the size of the measured area at a given distance; this ratio is not a synonym for accuracy. Emissivity settings may be fixed or adjustable depending on the model and target surface. Thermal imaging cameras, contact thermometers and core-temperature probes are excluded from this category. Industrial buyers select infrared thermometer models based on temperature range, measurement accuracy, distance-to-spot ratio, emissivity configuration, and site conditions including ambient lighting, surrounding temperature and data documentation requirements.
