Description

Orbisphere 311XX - the ultimate in O
2
sensors
The patented polarographic sensor design 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, this sensor provides fast, accurate oxygen measurements, in gaseous or liquid samples.
A wide range of temperature and pressure ranges is made possible by the 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 these 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
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
