IROS 05 with Attenuated Total Reflection (ATR) probes designed for harsh application conditions

 IROS 05 FTIR _4.jpg The spectrometer can be equipped with an adapter for fiber optic 
probes with a universal connector (SMA) and various high-quality fiber optic probes. 
Immersion fiber optic probes are suitable for monitoring processes in 
laboratory-scale plants as well as in commercial reactors. They allow 
you to increase the accuracy of chemical processes analysis in real 
time and reduce the cost of process control. 
Fiber optic ATR probed can be equipped with various tips: Diamond, 
ZnSe, Si, ZrO2

Key features:

  • High efficient transmission in parts of the near and mid infrared spectrum
  • ATR probe tips without dead zones
  • High reliability for industrial applications in harsh environments up to 250 °C
  • High pressure resistance
