We have been performing odor measurements in our accredited laboratory for businesses, industry and filter producers for over 15 years.

Our laboratory in Salzburg is accredited for performing odor measurements as per EN 13725 in business, industry and by filter systems.

We thank the producers of the Olfactometer, Mannebeck TO8, from the company ECOMA GmbH, for allowing us to use the information contained in this chapter.

Olfactometry is an effect-based measuring system, which analyses the effect of odors on humans. Odor samples are offered in a controlled environment and their effect on humans is then recorded. An olfactometer is in effect a dilution system, where an odorous air sample is diluted with odor-free clean air. This dilution is then offered to the test persons (smell-testers) for sampling.

Using the odor measurement the following can be determined:

• Odour concentration
• Odour intensity
• Hedonic effect

We use the newest multi-person-olfactometer of the type Mannebeck TO8 produced by the company ECOMA GmbH to measure odors from a wide variety of areas:

• Biofilters
• Air Emission Filters
• Waste Treatment Plants
• Food Industry
• Waste Water Treatment Plants
• Gastronomy
• Wood Chip Industry
• Pharmaceutical Companies

The measurements, performed with the olfactometer and the participation of test persons, are subject to strict standards. These are set in the olfactometric measurement procedure in the guidelines set by the Association of German Engineers, VDI Guidelines 3881 and 3882 as well as the European Norm DIN EN 13725. The olfactometer TO8 and the procedure used fulfil these guidelines and ensure that olfactometry is an objective, generally accepted and reliable method of measurement.
