The digital, infrared Impac® IS 5 and IGA 5 pyrometers are ideal for fast heating processes and measuring short temperature peaks. The pyrometers feature a 2 ms response time and you can choose from a laser-targeting light or viewfinder for precise alignment. Set parameters (emissivity, exposure time, and analog output) directly on the devices or via your PC using InfraWin software. You can also log data and analyze the complete temperature measurement process from your PC. 


  • Measure short temperature peaks and fast heating processes
  • Precisely target measuring objects
  • Achieve high accuracy
  • Log and analyze data
  • Detect small measuring objects
  • Store maximum values


  • Very small spot sizes, minimum 0.5 mm
  • Laser-targeting light or through lens viewfinder are available
  • Analog output adjustable 0 to 20 mA or 4 to 20 mA
  • Built-in maximum value storage
  • Digital interface
  • Bus capable with RS485 interface
  • Small dimensions

Select specifications are shown below. Please see product data sheet for additional specifications.
