The Neutronics 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.

The robust design of the Neutronics zirconium oxide sensor gives this analyzer the ability to rapidly measure oxygen through large step changes in concentration and the ability to accurately measure ppm concentrations of oxygen within seconds after exposure to air. When heated to an elevated temperature, the rapid-response zirconium oxide sensor produces a predictable electrical output in response to changes in the partial pressure of oxygen. The sensor is a solid-state device that utilizes yttria-stabilized zirconium (YSZ),
