A few professional temperature measurement devices include both an IR thermometer and K thermocouple. The IR thermometer excels at non-contact temperature measurement, allowing users to gauge the temperature of an object from afar. The IR thermometer is complemented by the K thermocouple, which allows users to measure internal temperatures of solids and liquids.

Measuring Temperature with an IR Thermometer and K Thermocouple

IR thermometers operate by measuring an object's infrared radiation. The amount of infrared radiation being emitted by the surface of an object (for most objects that are warmer than minus 273° Celsius) can be converted into a value that corresponds to the surface temperature of that object. In many cases, the surface temperature of an object is related to the internal temperature of that object-- where abnormally high surface temperatures may correspond to aberrant internal conditions or faulty components.

K type thermocouples are reliable devices for measuring the internal temperature of a solid or liquid. They are classified as contact thermometers. A thermocouple functions by creating a voltage between two dissimilar metals that are at different temperatures. The voltage that is created between the metals relates to the temperature of the object that is being measured.

By pairing an IR thermometer and K thermocouple in a single device, users have the ability to measure the temperature of almost any object in their environment. A few manufacturers of IR thermometers, including Radiant Innovation Inc. and Raytek, make handheld thermometers that contain both an IR thermometer and a contact probe. Affordable consumer models are available, as are more expensive and fully featured professional models.
