  • Adjustable exposure time 
  • Compact housing

Details

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

The instruments differ in their specification: the IN 5 is a digital pyrometer in two wire format. This format combines the high accuracy of the digital signal processing with the simple connection and operating with two wires.

Additionally to the analog output the plus types are digital pyrometers equipped with a digital interface, enabling temperature indication and storage on a PC. Also a temperature sub range can be configured and the instrument parameters can be adjusted remotely.

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.

For optimal match of the instrument to the application (size of the measuring object, distance) different optics are available.

For a precise alignment of the pyrometers to the measuring object, plus types are equipped with a laser targeting light.

Typical Applications:

  • Plastics
  • Fluids
  • Rubber
  • Painted parts
  • Paper
  • Asphalt
  • Ceramics
  • Wood
  • Textiles
  • Glass
  • Food
  • Coated metals
