SWG 300 IND Continuous Emission Monitoring System (Indoor)

NO NO2 SO2 CO2 CO CH4 O2 H2S H2
  • Low sample flow extraction of only 50 l/h, to enhance the operation of sample gas preparation
  • Use of optimized NDIR technology with improved accuracy and without zero offset
  • O₂ measurement with a long-life electrochemical or a paramagnetic sensor
  • True NOx and SO₂ measurements through use of heated gas sampling probe and gas sampling line
  • Heated and temperature regulated acid mist catch & drain system for raw flue gas measurements with high acid aerosols
  • Complete heavy duty sample conditioning system for extractive cold and dry system
  • Ready to log, display and transfer data from dust concentra- tion monitor DM 401 and flow rate monitor DF 252.
Basic-Equipment

  • Efficient sample gas filtration using PTFE sintered particulate filter
  • Condensate monitoring and alarm on display and gas sampling stop in case of alarm
  • Prepared for 10 % H3PO4 dosage in case of auto-cal or low SO₂/NO₂ measurements
  • Strong sample gas pump with sample gas flow monitoring and alarm
  • Filtration of acid gases to protect the internal sample gas flow sensor
  • Solenoid valve for auto-zero with clean ambient air
  • Solenoid valve for calibration gas, with aluminum fine pressure regulator at cal. gas inlet port
  • Main control unit 19" – 4U with human machine interface, prepared for measurement modules
