Is Objective Odour Measurement Possible?

Odours are subjective, varying from person to person. This makes them hard to measure. But objective odour measurement is possible. The key is using trained assessors, standardised methods, and accredited lab testing. UKAS accreditation to BS EN 13725:2022 ensures results are reliable and accurate. This makes odour data useful for planning, permitting, and environmental investigations.
