Digital infrared thermometers are heavily used by many different industries. The components of IR thermometers are relatively simple, sometimes including little more than the IR sensor, supporting analog and digital electronics and an accompanying computer chip. The simplicity of those components offers designers a versatility that can be used in a variety of professional settings.

The most common digital infrared thermometers in industrial use may be fixed-mount IR thermometers. Through the design specifications of fixed-mount thermometers differ from manufacturer to manufacturer, fixed-mount thermometers generally include a small, high-quality IR sensor that sends data to an equally tiny electronics box. The electronics box serves two functions: it sends the data from the sensor to a remote computer system for recording and monitoring, and it receives data from the computer system to control the sensor's settings.

Other popular digital infrared thermometers are handheld, portable measuring devices. They often house the same technology as the fixed-mount systems, but in a form that can be easily held, used, or stored in a holster or tool chest. Many also include a laser for increased target accuracy.

How Digital Infrared Thermometers Work

IR thermometers work by measuring the amount of IR radiation that is being emitted by an object. The data is then interpreted as the temperature of the surface of the object, which is then displayed on the LCD screen. Most handheld IR thermometers have a temperature accuracy of two percent, and a resolution of a tenth of a degree.
