Orbisphere 311xx Oxygen Sensors

The unique polarographic sensor design of the Orbisphere 311xx Sensors is a proven performer wherever knowledge of O2 content is critical.
From beverage quality control to corrosion monitoring in power generators, from package sampling to chemical manufacturing, these sensors provide fast, accurate oxygen measurements, in gaseous or liquid samples.

A wide range of temperature and pressure ranges is made possible by Orbisphere’s exclusive valve seat sealing, whereby the sensor cathode is mechanically tensioned against a ceramic valve seat to ensure the integrity of the seal. This design enables a vanishingly small residual signal, for improved accuracy.

All Orbisphere oxygen sensors use the deep-draw membrane mounting method for a uniformly thin layer of electrolyte for faster response and superior stability. Coupled with a screw-on protection cap, the sensor provides in-service intervals of up to a year.

• Guard Ring Electrode design improves speed of response and reduces interferences.
• Installs in-line for process control, or in flow chamber for spot measurement.
• Cable detaches at sensor end for installation and maintenance flexibility.
