- The Neutronics Model OA-1S+ is a portable analyzer that accurately measures oxygen in the range of 50 ppb to 100%. Featuring the Neutronics rapid response zirconia oxide sensor with its extremely fast response and high accuracy, the Model OA-1S+ can be exposed to air and quickly read ppb oxygen in a variety of background gases, including Nitrogen, Argon, and Helium. The OA-1S+ is designed to measure oxygen concentrations in clean gases that do not contain hydrocarbons or carbon monoxide.
- PPB to 100% measurement range
- Rapid-response Neutronics zirconium oxide sensor
- Electropolished SS tubing and orbital weld fittings
- Unaffected by position or motion
- 5 to 7 year sensor service life
