The odor pollution in the metal material products factory mainly comes from toxic and harmful gases generated by the production process. The German AIRSENSE online odor monitor effectively monitors the odor pollution in the factory area and surrounding areas, which can achieve continuous online monitoring, reduce the harm of pollution to factory employees and surrounding residents, and also play an important guiding role in enhancing the corporate image of the factory area.

The OLFOSENSE online odor concentration monitoring system consists of a combination of multiple sensor arrays, including 4 types of MOS metal oxide sensors, 1 type of PID photoionization detector, 2-4 types of electrochemical sensors, etc. The monitoring results can display single gas concentration values of hydrogen sulfide/ammonia, total organic volatile compounds of VOCs, or user selected single concentration values of odor gases (1-2 types), as well as dimensionless odor concentration OU values. On site or remote monitoring center, real-time and historical monitoring data can be viewed through the network.
