Electronic noses capability to simulate human olfaction makes these instruments perfect for directcharacterization of odours directly where their presence is lamented. However, the lack of regulation aboutinstrument minimum requirements and standardization limits their widespread diffusion for the determinationof the odour impact relevant to a specific industrial activity. This paper aims to propose a testing procedure forverification of electronic nose performance in environmental monitoring. In order to test instrument capabilityof detecting odour presence, specific tests were defined and carried out to determine instrument lowerdetection limit towards common environmental odours and the repeatability of responses to a given stimulus.
