St. Croix Sensory remains open and committed to the success of your project needs throughout the COVID-19 pandemic.
For the safety of our clients and staff, we have outlined our “Best Practice Recommendations” for the use and care of the Nasal Ranger Field Olfactometer, Odor Sensitivity Test Kit and odor sampling equipment.
The Odor Sensitivity Test Kit is used to test the olfactory ability of your odor inspection staff. This portable, simple to use kit makes it easy to screen potential noses and continually monitor their olfactory acuity.
St. Croix Sensory’s Odor Sensitivity Test Kit is utilized to test the noses of potential odor inspectors. The n-butanol odorant pen dilution series provides a standard measure of sensitivity.
It takes approximately 20-minutes to complete the test for one user.
