TNO MEP - Odor measurement system

TNO MEP in Apeldoorn, The Netherlands performs smell measurements all over The Netherlands using their smell measurement system.

Smell measurements are conducted to observe how much "smell" a company produces. This cannot be performed by robotic electronic noses. Current measurement practice uses a panel of "sniffers" that is offered diluted smells. The diliution is gradually lowered until a "sniffer" can detect the smell conclusively. Based on the average dillution among the panel can be determined how "strong" the smell was.

TNO has a small furnished truck specially for the purpose of delivering diliytions of smell to a panel of "sniffers". The truck consists of a dilition system, tubing and buttons for each sniffer.

De software, written especially for TNO, makes sure that the correct dilutions are offerd to the panel and that the results are automatically stored in a database and trnslated in several reports. Reports for the client and ofr quality control are produced with the press of a button.

Important aspect of this project was the fact that the software tries to conserve as much smell and sniffing time as possible. The results generated in the truck are almost instantly visible in the office at TNO and can be further ananlysed there.
