Scentinal is the world’s only air quality monitoring station that provides simultaneous pollutant and odour
measurements. Data from individual sensors is processed by Scentroid’s chemical and olfactometric
correlation system to determine odour concentration in OU/m3. The system uses a neural network learning
algorithm to determine odour concentration from chemical readings.
Olfactometric measurements, using the Scentroid SM100 Field Olfactometer, are collected periodically
(monthly, bi-monthly, or semi-annually) and are inputted into the learning algorithm along with recorded
chemical composition. This sophisticated algorithm will then create a non-linear relationship between
chemical readings and odour concentration. This data is used to teach the network and enhance the accuracy
of odour concentration prediction from chemical composition. The advantage of this system over other
competing technologies such as E-Noses is that chemical to odour concentration is based on routinely
gathered olfactometric data and therefore is always up to date regardless of changes to the plant processes.
