Description

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. Guard Ring Electrode Design An auxiliary guard ring electrode surrounds the working electrode to shield against the influence of other gases and improve stability. Rugged Construction Use for harsh chemicals, hot CIP and high pressure situations. Flexibility Installs in-line for process control, or in flow chamber for spot measurement. Cable detaches at sensor end for installation and maintenance flexibility. From trace levels to super saturation Unrivalled detection limit of ± 0.1 ppb or 100 ppt
