純水溶氧感測器(電化學法) Hach Orbisphere Electrochemical Oxygen (O₂) Sensor, PEEK, 20 bar, EPDM O-Ring, with fast temperature changes option
產品編號31110A.02
Orbisphere 311XX - the ultimate in O2 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.
精密感測器設計可於氣體或液體樣品中提供快速、準確的氧氣監測。

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.
獨特的閥座密封設計可達到寬廣的溫度範圍和壓力範圍。

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. 氧氣感測器採用深拉膜安裝方法,形成均勻的薄電解質層,更快的反應和優異的穩定性,再加上旋入式保護蓋,感測器的使用壽命可達一年。

產品介紹
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
