The Neutronics 3100 Percent Oxygen Analyzer is a compact analyzer that features the Neutronics rapid response zirconium oxide sensor and a measurement range of 0.1 ppm to 100% oxygen. With its extremely fast response time and high accuracy, the Model 3100 delivers reliable performance for a wide variety of oxygen gas measurement and critical process control applications.

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 zirconia (YSZ), a zirconium-oxide based ceramic in which the crystal structure of the zirconium oxide is made stable at room temperature by the addition of yttrium oxide.
