SWG 200 CEM
Stationary gas analysis system for continuous process gas and emission monitoring
Outstanding benefits:
- Use of optimized NDIR technology with improved accuracy without zero point drifts
- O₂ measurement with an electrochemical or a paramagnetic sensor
- Automatic zero point in clean ambient air through separate calibration gas inlet
- Automatic calibration for up to four gas cylinders
- Double stage Peltier gas cooler with two automatic condensate pumps
- Cold/dry gas extraction at a low flow volume of 1 l/min
Temel Donanım
