On August 25, 2023, our company's engineers visited a company in Shanghai and completed the installation and commissioning of three sets of German Olfosense odor monitoring systems. In order toConvenient and better application devices,In depth training was conducted on-site with the company's technical personnel,Detailed explanations were given on the operation and maintenance of the equipment. The customer is mainly used to monitor the exhaust emissions from the factory chimney, including ammonia, hydrogen sulfide, VOC, and odor OU. Self monitoring is necessary to establish a good corporate image.

The OLFOSENSE series odor monitoring device is a system developed by AIRSENSE in Germany specifically for monitoring environmental odor pollution. It can monitor the concentration values of hydrogen sulfide, ammonia, and total organic volatile compounds (VOCs) in a single gas and the dimensionless OU value of odor concentration in real time. The system mainly relies on a mixed array of multiple types of sensors for analysis and monitoring. There are four types of MOS metal oxide sensors, one type of PID photoionization detector, and two types of electrochemical sensors. It can be portable for mobile monitoring or continuously monitored online 24 hours a day. Multiple devices are networked and distributed for odor monitoring, which can achieve all functions from gas collection, monitoring, model matching, analysis and calculation, result display, data transmission, and backend data management.
