Analyzer AIR LF measure the composition of landfill gas and biogas with linear NDIR technology.
This method of measuring by absorption of infrared radiation is highly resistant and provides stable measured data.
Knowledge of the exact composition of gas is important for more efficient production.
AIR LF analyzer allows transparent monitoring of measured data by connecting it to cloud service
