The Impac IN 5 and IN 5 plus pyrometers are specifically designed for non-contact temperature measurements on non-metallic surfaces and painted, coated, or anodized metals.

The version IN 5-L plus is equipped with optics with better fields of view for the measurements of small objects.

The high-speed version IN 5-H plus has a shorter exposure time of only 10 ms and is suited for fast-measuring tasks.


  • Operate in rough industrial environments
  • Digitally store and process temperature data
  • Adjust emissivity and exposure time directly in the instrument
  • Optimally match instruments to the right applications
  • Remotely adjust instrument parameters and configure a temperature subrange (IN 5 plus only)


  • High accuracy due to digital linearization of the ouput
  • Compact housing
  • Various optics available
  • Digital interfaces RS232 or RS485 and laser targeting light sighting system (IN 5 plus only)
  • Simple connection and operating with two wires (IN 5 only)

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