The Impac® IS 12-TSP and IGA 12-TSP are extremely precise transfer standard pyrometers that can inspect calibration sources. The detectors in TS pyrometers are thermostatically controlled to achieve high precision. This means measurements are, to a large extent, independent of surrounding temperature variations and a resolution of 0.01°C can be achieved.

The IS 12-TSP or IGA 12-TSP are available in several temperature ranges between 200 and 3000°C. You can also select from various spectral ranges. This enables use with calibration sources that check pyrometers with silicon or indium gallium arsenide detectors.


  • Accurately inspect your calibration sources
  • Use with calibration sources with which pyrometers with silicon or indium gallium arsenide detectors can be checked
  • Achieve high precision
  • Ensure that temperature values, as stipulated by national institutes, can be transferred to your own calibration sources to guarantee traceability to the ITS90 international temperature scale
  • Guarantee adherence to high technical specifications


  • Temperature ranges between 200 and 3000°C
  • Resolution of only 0.01°C
  • Built-in, five-digit LED display
  • Digital interface
  • Focusable optics

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