HIGH END 24/7 gas analysis
With SWG 200 CEM (Continuous Emission Monitoring) we offer you a cost-effective, reliable system for emission and combustion monitoring.
Features:
Use of optimized NDIR technology with improved accuracy and without zero offset
O₂ measurement with an electrochemical or a paramagnetic sensor
Automatic zeroing using clean ambient air
Automatic calibration for up to 4 gas cylinders
Double-stage Peltier gas cooler with 2 automatic condensate pumps
Cold/dry gas sampling with low sample flow volume of only 1 l/min
Benefits:
Make your combustion process more cost-effective.
Get the data to show your organization cares about the environment.
Applications:
Diesel engines, methane/natural gas boilers, landfill gas/bio-gas CHPs, bagasse and biomass boilers and others.
