Infrared Thermometer Model CA879

The Infrared Thermometer Model CA879 is a non-contact temperature measuring instrument. It provides precision measurement with its laser target feature. To measure the temperature of an object, simply point the gun at the surface of the object and the temperature will appear on the digital display. The thermometer has an automatic shut-off feature. Shut-off will occur approximately 10 seconds after the trigger is released.

All objects whose temperature is higher than absolute zero (-273.15 K) emit infrared energy. This energy radiates in all directions at the speed of light. When the gun is pointed at an object, the probe’s lens senses this energy and focuses it onto an infrared detector comprised of a thermocouple stack. The detector produces a voltage signal proportional to the amount of energy received, and therefore proportional to the object’s temperature.
