Orbisphere 311XX - the ultimate in O2 sensors 精準監測氧氣量的感測方案
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.
極譜分析法感測器設計性能卓越，特別是針對需要精確測量氧氣量的領域。從飲料品質控制到工業發電機腐蝕監測，從包裝取樣到化學物質生產，Orbisphere 電化學方法溶氧感測器能夠快速、準確地測量氣態或液態樣品中的氧氣濃度。

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能夠適應寬廣的溫度和壓力範圍。此設計透過機械張力將感測器陰極壓緊在陶瓷閥座上，進而確保密封的完整性。此設計能夠產生極小的殘餘訊號，進而提高測量精確度。

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片安裝方式，形成均勻薄的電解液層，進而達到更快的反應速度和更優異的穩定度。配合旋入式保護帽，此感測器的使用期限可長達一年。
