definition
  • The Model PRT-5 (Precision Raditaion Thermometer) is a battery-powered, infrared radiometer. Extremely versatile, this instrument makes highly sensitive, non-contact temperature measurements in any selected range between -50?C and 150?C. The PRT-5 can be employed from aircraft, land vehicles, ships or other platforms. It is completely portable, requires no set-up time, and does not depend upon external power. Typical targets for the PRT-5 are sea surface, clouds, sky background, terrain and similar large-area subjects that are difficult or impossible to measure by conventional methods. The PRT-5 consists of a 3.5 pound optical head and a rack-mounted, solid-state electronic control unit. The optical head may be hand-held, by means of a pistol grip attachment, or tripod mounted. It is linked to the electronic control unit by an 8-foot interconnecting cable. When not in use, the optical head is stored in a rugged, protective carrying case, which also contains the control unit and all cables. The standard PRT-5 has a 2-degree field of view, a spectral range of 8 to 14 microns, and a three-range, overlapping temperature scale graduated in degrees C or F. This instrument provides a target spot size of 35 feet at typical working distance of 1,000 feet. With all versions of the PRT-5, measurements are independent of distance as long as the target fills the instrument?s field of view.
