The most basic design consists of a lens to focus the infrared energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons.

Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or other controlled atmosphere; or in applications where a fast response is required.

Infrared thermometers can be used to serve a wide variety of temperature monitoring functions. A few examples provided to this article include:

• Checking mechanical equipment or electrical circuit breaker boxes or outlets for hot spots 
• Checking heater or oven temperature, for calibration and control purposes.
• Detecting hot spots / performing diagnostics in electrical circuit board manufacturing 
• Checking for hot spots in fire fighting situations 
• Monitoring materials in process of heating and cooling, for research and development or manufacturing quality control situations 

There are many varieties of infrared temperature sensing devices available today, including configurations designed for flexible and portable handheld use, as well many designed for mounting in a fixed position to serve a dedicated purpose for long periods.

Specifications of portable handheld sensors available to the home user will include ratings of temperature accuracy (usually plus or minus a degree or two), plus some other not so obvious measurements. The distance to spot ratio (D:S) measures the diameter of the temperature measurement area as it relates to the distance between the device and the surface being read. For instance, if your target area was one inch wide and you could get no closer than 12 inches to your target, you would need a sensor with a D:S of 12:1 or greater. Another feature is whether the sensor has a fixed or adjustable emissivity setting. If fixed, you would not get accurate readings from shiny surfaces (because most sensors are calibrated for non-shiny surfaces). Fixed emissivity sensors can be effective on shiny objects by just using tape or paint on your surface to compensate.
