Sniffer4D OU Sensing Module: Detect Odor Fast for Field Investigation Missions
The Sniffer4D OU Sensing Module gives odor investigation teams a fast, under-30-second reading dedicated to general odor detection, installing into a single slot on the Sniffer4D Nano 2 Plus Base Unit. It uses an electrochemical sensor tuned specifically to detect odor causing compounds in the field.
Rated for a 36 month service life and operable from -40 to 55 degrees Celsius, it holds up across some of the widest environmental conditions in the Sniffer4D catalog, useful for programs running odor investigations across variable climates and seasons. Its wide humidity tolerance, up to 95 percent RH, supports both dry and humid deployment sites.
Key Features and Benefits
- Electrochemical sensing: measures general odor concentration with high precision accuracy.
- 0.1 ppm detection limit: catches low level odor events across sites.
- 10 ppm linear range: covers trace levels through elevated odor concentrations.
- Under 30 second response: delivers fast readings during active flight operations.
- 0.01 ppm resolution: captures fine shifts in odor gas concentration.
- 36 month service life: supports extended field deployment before replacement.
- Wide temperature range: operates reliably from -40 to 55 degrees Celsius.
- Wide humidity range: functions up to 95 percent RH non-condensing conditions.
- Single slot install: adds odor sensing without claiming the full array.
The OU Sensing Module exists to give odor investigation programs a fast, dependable way to trace complaints back to a source without a lengthy wait for readings. Its wide temperature and humidity tolerance means it holds up across seasonal and regional deployment conditions.
