What Does OU Stand For?
OU stands for Odor Units
Odor Units (OU) is a standardized measurement used to quantify the concentration of odor-causing substances in the air. This metric reflects the intensity of an odor and is typically expressed in terms of the number of odorless air volumes required to dilute an odorous sample to the threshold of detection by the average human nose. OU is widely utilized in environmental monitoring, industrial processes, and regulatory compliance to assess and manage odor impacts on communities and ecosystems.
