- The Model OA-1 is a portable analyzer that accurately measures oxygen in the range of 0.1 ppm to 100%. Featuring the Neutronics rapid-response zirconium oxide sensor with its extremely fast response and high accuracy, the Model OA-1 can be exposed to air and within seconds read ppm oxygen in a variety of background gases, including Nitrogen, Argon, and Helium. The OA-1 is designed to measure oxygen concentrations in clean gases that do not contain hydrocarbons or carbon monoxide.
- PPM to 100% measurement range
- Rapid-response Neutroniccs zirconium oxide sensor
- Suitable for a wide range of operating gas temperatures
- < 15 seconds from air to 50 PPM
- 5 to 7 year sensor service life
