The Raytek GP infrared pyrometers come with two types of rugged sensors: GPR and GPS. They both provide standard or close focus optics and target temperature readings with 1% accuracy.
In addition, the laser sighted GPS model provides alignment in hard-to-reach locations, or to small or distant targets. The GPS is capable of measuring targets as as small as 4.5 mm (.18 in) and 35:1 spot size at 200 mm (8 in) distance, for the close focus version of the sensor.
The GPS targets temperatures from -18 to 540ºC (0 to 1000ºF) with 1% accuracy, and has a standard optical D:S ratio of 50:1. The GPS integrated coaxial Class 2 laser is connected to the remote activation switch box via the included 4 m (13 ft) cable. An additional 8 m (26 ft) of cable is also included to connect the switch box to the GP monitor.
