Offering accredited services to the highest possible quality standards

Olfasense has always aimed to be an innovator, so it is fitting that we pioneered ISO 17025 accreditation for odour – the main and most important standard for calibration and testing laboratories globally. We obtained our first (ISO 17025) accreditation certificate on 28 September 1993 for our Amsterdam laboratory.

We now run four accredited testing laboratories for olfactometry in accordance with the European Standard EN 13725. Our companies provide both accredited odour sampling and odour analyses services. Please see our scopes of accreditation for details on the accredited services we can offer you:
