New Technology in Stink-o-Meters

Here are some of the newer technologies in odor testing.

CogniScent’s ScenTraK™ technology can identify and discriminate a broad range of unique odors with high levels of accuracy. ScenTraK™ detects for explosives, chemicals, biological matter including building molds, and industrial compounds found in manufacturing environments. ScenTraK™ technology can indicate a “hit” for target odors within 10 seconds of sampling while remaining on the job indefinitely. The system is portable, durable, accurate and cost effective, making it ideal for broad deployment to security agencies, first responder organizations, HAZMAT teams and environmental & industrial process engineers. Principal funding for the development of the ScenTraK™ core technology has been received from the Defense Advanced Research Agency (DARPA) and the Homeland Security Advanced Research Projects Agency (HSARPA) to provide a lightweight autonomous chemical identification system.


The Nasal Ranger® Field Olfactometer is the “state-of-the-art” in field olfactometry for confidently measuring and quantifying odor strength in the ambient air. The Nasal Ranger® Field Olfactometer, a portable odor detecting and measuring device, determines ambient odor “Dilution-to-Threshold” (D/T) values objectively. Field olfactometry can be used as a proactive monitoring or enforcement tool for confident odor measurement at property lines and in the neighboring community. The Nasal Ranger® Field Olfactometer, as a nasal organoleptic instrument, provides field olfactometry with a scientific method for dependable ambient odor quantification. A Nasal Ranger® Field Olfactometer creates a calibrated series of discrete dilutions by mixing the odorous ambient air with odor-free (carbon) filtered air. Field olfactometry defines each discrete dilution level as a “Dilution-to-Threshold,” D/T, ratio. The “Dilution-to-Threshold” ratio is a measure of the number of dilutions needed to make the odorous ambient air “non-detectable”.


Stink-o-Meter. Is this what MDNR is using? If so, maybe we could hold a bake sale or something to raise funds for MDNR so they could upgrade their 'equipment'.
