Continuous emissions monitoring for glass manufacturing - Glassware

Process control and emissions monitoring in a glass manufacturing plant is a challenge due to high temperature in the flue gas. The OPSIS DOAS system provides the glass industry with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method that uses an optical path to measure across the duct.

A single OPSIS system will measure all relevant gas componensts such as NOX, SO2, CO, CO2, H2O, O2, and others.


  • Combines the benefits of DOAS, FTIR, and TDL technology
  • No sampling required, non-contact measurement system
  • Automatic QAL3 checks and gas calibration twice per year
  • Operates with a minimum of maintenance
  • Low energy consumption
  • Internationally approved
  • Thousands of systems installed worldwide
  • Experienced and skilled service network
