In December 2006, Olores.org visited the facilities of St Croix Sensory in Lake Elmo, Minnesota, USA. St. Croix Sensory is a sensory testing and training company that specializes in odor testing of air samples, commercial products, and materials and in training of odor assessors, monitors, inspectors, and investigators. Likewise, St. Croix Sensory manufactures state-of-the-art odor sampling and odor measurement equipment. Their products set the standard in odor sampling, testing, and measurement.
In December 2006 we paid a visit to this firm to know a little bit more about their activities. During this visit, we could have a look to the process of manufacturing the olfactometer AC´Scent. The AC´Scent olfactometer has incorporated its own fresh air pump device with a special filter to assure you get an odorless air for testing, this is a special feature that makes the difference with other olfactometers in the market which usually come with no pump incorporated. Other devices might be smaller but at the end you need to acquire also an air pump and active carbon filters.
