NASAL RANGER

Nasal Ranger is the “state-of-the-art” in field olfactometry for confidently measuring and quantifying odor strength in the ambient air. The portable Nasal Ranger Field Olfactometer determines ambient odor Dilution-to-Threshold (D/T) concentration objectively with your trained nose.

The Nasal Ranger Package includes the Nasal Ranger with Nasal Mask, Odor-Filter Cartridges, Shoulder Strap, Carrying Case, as well as and extra pair of Odor-Filter Cartridges, 10-Comfort Mask Seals, and 10-Isopropyl Alcohol Mask Wipes.

Features

FAQ

1

Where can I buy a Nasal Ranger?


The Nasal Ranger may be purchased by contacting Odosys Services directly.

2

What does the Nasal Ranger measure?

The Nasal Ranger Field Olfactometer quantifies the perceived odor level as dilutions-to-threshold (D/T).  This is determined as the number of dilution needed to make the ambient air odor just detectable.

3

Who can use the Nasal Ranger?

Almost anyone can use the Nasal Ranger!  Commonly, air quality control managers, municipality managers and regulators, facility operators, and citizen groups are using the Nasal Ranger to quantify ambient odors.

4

How often do I need to change the odor filter cartridge?

The life of the odor filter cartridge will depend on how often it is used and the strength of the odors that it is filtering.  A reasonable rule-of-thumb is to replace the cartridge after 200-hrs of field use.  Stronger odors may require more frequent replacement.  Please see this video (right) for additional information and demonstration of the filter replacement.

5

What is the difference between Field Olfactometry and Laboratory Olfactometry?

Both threshold results are based on the dilution-to-threshold principle and are thus a similar measure.  Laboratory olfactometry, following ASTM E679 and EN13725, is best utilized when source odors are being measured (e.g. source stack emission).  Air dispersion modeling is then utilized to predict the impact of those source odors on the community.  Field Olfactometry is performed to quantify the odors in the community; therefore, it is a direct measure of the community impact at that specific moment in time.

6

How frequently should my Nasal Ranger be calibrated?

The Nasal Ranger should be sent to Odosys Services for annual calibration verification.
