JNOX NO2 to NO Sample Gas Converter


  • NOx converter for extractive gas analysis
  • For emission and process monitoring
  • Conversion of NO2 to NO for NOx-measurement
  • Enables the use of infrared-analysers
  • For dry sample gases with unheated inlet or for hot and humid sample gases with heated inlet


  • Variable applicable due to different housing and equipment versions
  • Long lifetime of the converter cartridge of approx. 10^6 ppmh NO2
  • High conversion ratio
  • Fast response time due to low dead volume
  • No CO-Emission with molybdenum containing converter filling material
  • High flow performance
  • Low cross sensitivities


  • In 19'', wall mounting or portable housing
  • Efficiency of converter > 96 %
  • Digital temperature indication and status LEDs
  • Status contact
  • Conversion material carbon or metallic (molybdenum containing)
  • Model with unheated or heated bypass connection upstream conversion for additional measurements or fast response times
  • Model with local or remote controllable unheated 2/3-way solenoid valve to bypass the converter cartridge for calibration or test gas feeding
