The GP Series, consisting of GPR and GPS models, is a versatile, two-piece temperature monitoring system that combines a compact, value-priced monitor with an infrared sensing head. The heart of the system is the 1/8 DIN GP monitor which provides advanced infrared processing capabilities including peak and valley hold, averaging, and a user-adjustable offset.

The Compact GPR model is available with standard or close focus optics and provides target temperature readings with 1% accuracy.

In addition, the GPS model features laser sighting and standard optical Distance to Spot (D:S) ratio of 50:1, allowing for easier sensor alignment in hard-to-reach, small or distant targets. 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.

Key Features:

  • Read temperature ranges from -18 to 538°C (0 to 1000°F)
  • Available with standard or close focus optics
  • Withstand ambient temperatures without cooling: monitor up to 50°C (120ºF) and the sensing head up to 65°C (150°F) .
  • Accessories for air purging and water/air cooling
  • Compact 1/8 DIN digital monitor with large 4-digit display
  • Monitor and sensor functions configured on front panel
  • Response time: 300 mSec
  • Adjustable emissivity and T-ambient parameters
  • Adjustable dual setpoints, deadband alarm outputs and optional mechanical relays
  • Field interchangeable sensing heads
