This paper summarizes the development and operation of a Mask Scentometer and reports air dilution ratios measured during its use, which were used to establish the devices dilution-to-threshold settings. The Mask Scentometer is a facial respirator that has been modified to operate conceptually like the Barneby and Sutcliffe Box Scentometer. The Mask Scentometer is comprised of a -face respirator with two modified spin-on cartridges, one per side, which facilitate mixing ambient air with filtered air for presentation to an odor assessor at user-selected dilution ratios. The flow-weighted average dilution ratios produced within the Mask Scentometer were 18, 4.5, 2, 1, and 0.35. Investigators using the Mask Scentometer to measure ambient odor concentrations are advised to use these dilution-to-threshold values.
