Description
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.
