An infrared thermometer is a thermometer that infers the temperature from a portion of the thermal radiation that is sometimes called black body radiation emitted by the object being measured. They are sometimes called laser thermometers because lasers are used to help align thermometers, non-contact thermometers, or temperature guns to describe the device's ability to measure temperature from a distance. By knowing the infrared energy emitted by the object and its emissivity, the temperature of the object can usually be determined within a specific range of its actual temperature. Infrared thermometers are a subset of devices called "thermal radiation thermometers".

But sometimes, especially near the ambient temperature, the readings may be reflected by the radiation from a hotter object (even a person holding the instrument) rather than the object being measured, and the emissivity may be incorrectly assumed.

Application of infrared thermometer box

The infrared thermometer can be used for a variety of temperature monitoring functions. Some examples provided include detecting clouds for remote telescope operation, checking the temperature and hot spots of mechanical or electrical equipment, measuring the temperature of a hospital patient without touching the patient, checking the temperature of a heater or oven, performing calibration and control, and checking for hot spots In terms of fire protection, materials are monitored during processes involving heating or cooling, and the temperature of the volcano is measured. When fever-causing diseases (such as SARS coronavirus and Ebola virus disease) are prevalent, infrared thermometers have been used to check the fever of arriving passengers without causing harmful transmission between the subjects.

During the 2020 COVID-19 pandemic, infrared thermometers are used to provide safe and accurate testing. Public health agencies such as the FDA have published rules in the United States to ensure the accuracy and consistency of infrared thermometers.

There are many types of infrared temperature sensing devices, which can be used for portable and handheld devices, and can also be fixedly installed.


Points to note when using infrared thermometer box

The environmental conditions of the thermometer have a great influence on the measurement results, which should be considered and properly resolved, otherwise it will affect the temperature measurement accuracy or even cause damage. When the ambient temperature is high and there are dust, smoke and steam, you can choose the manufacturer's protective cover, water cooling, air cooling system, air purifier and other accessories.

These accessories can effectively solve the environmental impact and protect the thermometer to achieve accurate temperature measurement. When determining accessories, standardized services should be required as much as possible to reduce installation costs. When in noise, electromagnetic field, vibration or inaccessible environmental conditions, or other harsh conditions, smoke, dust or other particles reduce the measurement energy signal, the fiber optic two-color thermometer is the best choice. Under noise, electromagnetic field, vibration and inaccessible environmental conditions, or other severe conditions, optical fiber colorimetric thermometers should be selected.
