Odor measurement includes the measurement of odor substance concentration using instruments and sensory tests using human olfaction!
Our company conducts analysis and evaluation based on the "Odor Control Law." Odors generated from factory operations and other business activities are measured according to the occurrence conditions, such as air, exhaust gas, and wastewater. The gaseous odors are diluted with odorless air, and the dilution ratio at which the odor is no longer detectable is referred to as "odor concentration." The Odor Control Law regulates odors based on the logarithm of the odor concentration multiplied by ten, known as the "odor index." 【Sensory Testing】 ■ Odor analysis by humans is conducted within 24 hours of sample collection. ■ Testing is performed by a panel of six members and odor judges. *For more details, please refer to the PDF document or feel free to contact us.
