There are many different types of thermometer modules for many different industrial and professional uses. Along with the traditional mercury thermometer, a few types of popular temperature sensing devices are infrared thermometers, digital thermometers, and thermocouples. All of the different types of thermometer modules can be divided into two broad categories: contact thermometers and non-contact thermometers.

Contact thermometers are devices that require either contact with the object or immersion in the object that they're measuring. For example, common bath thermometers require immersion in water in order to measure the temperature. Many contact thermometers are based on traditional mercury thermometer technology, though many current models use mercury substitutes such as LO-tox.

Non-Contact Thermometer Modules

Non-contact thermometers are capable of measuring the surface temperature of an object from a distance. The majority of non-contact thermometers use sensors that can measure the amount of infrared radiation that is being emitted by an object. Once the level of radiation is accurately measured, the values of the peak radiation wavelength and the total radiation energy can be converted into temperature data.

Non-contact thermometers are prized in many industrial applications for their ability to quickly scan an object and detect abnormal temperatures. Many industrial IR thermometers can, in a fraction of a second, measure the temperature of a small surface (less than two inches across) from over 50 feet away. Machinists, engineers, builders, mechanics, and firefighters all commonly utilize IR thermometer modules in the workplace.
