|Infrared Thermometer Types|
|Handheld Infrared Thermometers
Handheld infrared thermometers are one of the most popular types of infrared pyrometer. They are commonly used for portable applications although some models also feature an integral tripod mount. OMEGA offers a large variety of infrared thermometers in various shapes and form factors. Many of OMEGA handheld infrared pyrometers feature OMEGA's patented Circle Dot/Circle Laser sighting which clearly outlines the field of view of the thermometer.
|Pocket/Stick-Type Infrared Thermometers
Pocket or stick type infrared thermometers are extremely compact. They are normally small enough to be carried in a shirt pocket.
Infrared thermocouples are small low cost infrared sensors. They are unique in that they are self-powered and produce an output that mimics a thermocouple sensor.
|Fixed Mount Infrared Thermometer/Transmitters
Fixed mount infrared thermometers are commonly used in industrial processes where the thermometer can be mounted in a stationary position. Read the High Speed Fiber Optic Infrared Transmitter article for information about the OS4000 Series.
|Two Color-Ratio Thermometry
Given that emissivity plays such a vital role in obtaining accurate temperature data from infrared thermometers, it is not surprising that attempts have been made to design sensors which would measure independently of this variable. The best known and most commonly applied of these designs is the Two Color-Ratio Thermometer. This technique is not dissimilar to the infrared thermometers described so far, but measures the ratio of infrared energy emitted from the material at two wavelengths, rather than the absolute energy at one wavelength or wave band. The use of the word "color" in this context is somewhat outdated, but nevertheless has not been superseded. It originates in the old practice of relating visible color to temperature, hence "color temperature."
