The primary use of infrared thermometers is in measuring the temperature of a subject from a distance. The device is beneficial in situations where it is difficult to reach the object to record the temperature.

High-Temperature Infrared Thermometer has the adjustable high or low alarm. It has a fast and easy measurement. It has an automatic measurement range selection with a resolution of 0.1°C / °F. It has application in the steel industry and other metallurgical industries. The FT3700 and FT3701 are non-contact thermometers using infrared rays, accurately pinpointing the spot with a two-beam laser marker. The infrared temperature guns identify the surface temperature of an object by measuring the energy level of the infrared rays emitted from the object without physically coming in contact with it.
