Description

Orbisphere 311XX - the ultimate in O
2
sensors
The patented polarographic sensor design provides fast, accurate oxygen (O
) measurements in gaseous or liquid samples. Wide range of temperature and pressure ranges. Precise measurement from 0.1 ppb to 2000 ppm. Detection limit of ± 0.1 ppb or 100 ppt. Guard ring electrode design improves speed of response and reduces interferences. Calibrate in air for ease of use or against a sample of known oxygen content. Rugged construction for harsh environments. Sensitivity range meets any need, from trace levels to super saturation.
Sensor specifications depend on individual membrane chosen. Please click on the Downloads tab for the Installation and Maintenance Manual for appropriate sensor information.
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
