The Neutronics 4100 Trace Oxygen Analyzer is a compact analyzer for trace oxygen gas measurement and process control applications. With a measurement range of ppb (parts per billion) to 100% oxygen, this analyzer features a remote sensor module with the Neutronics rapid response zirconium oxide sensor. With extremely high accuracy, rapid response, and a long-expected service life, this analyzer is a low-maintenance solution that delivers reliable performance for critical applications that require oxygen contaminant monitoring in the ppb range.

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 ppb concentrations of oxygen within minutes 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.
