A review on non-dispersive infrared gas sensors ...

01/08/2016· A disadvantage of the NDIR gas sensor is its high detection limit. According to the Beer- Lambert Law, the transmission of an IR beam is proportional to gas concentrations. If the concentration of the target gas is low, the change of IR beam intensity would also be very small, and below the expected detection capacity of the detector. Therefore, increasing the inlet concentration of target gas ...
