Trace to Percent O2  |  0.1 PPM to 100% Range

Model OA-1

Portable/ Benchtop Series
Internal ZR100 Sensor

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.
