IROS 05i is a special FTIR spectrometer designed for work in harsh conditions. This model allows to solve a wide range of industrial problems, including process control, with the possibility of on-line (in-situ) monitoring of industrial processes (in reactors or pipelines) both for laboratories and industry facilities.


  • Completely tight metal case

  • Ports for connecting an external cooler and purging with inert gases to protect and stabilize the optical unit in difficult environmental conditions

  • Module for connecting fiber optic probes (up to two simultaneously)

Main Advantages

  • The ability to connect two probes, allows to work with the device in two-channel mode, monitoring simultaneously the processes taking place in two different reaction environments

  • The control software allows you to set flexible routines with continuous analysis and evaluation of the data obtained in real time

  • A wide range of probes designed for use in corrosive environments, at high pressures and temperatures, among others

  • The ability to install a high-sensitivity MCT detector with thermoelectric cooling will allow the device to be used where there is no possibility to use liquid nitrogen for cooling
