小型光學(xué)氧微傳感器配件專為各種定制應(yīng)用而設(shè)計(jì)。微型探頭的尺寸< 50 μm 至 140 μm，外徑范圍為 140 μm 至 900 μm。微型傳感器未安裝在任何額外的外殼中。裸露的玻璃纖維可以安裝到您自己的外殼、鋼管和微型呼吸計(jì)室等上。小外徑甚至允許插入植入式Venflon管中。此外，微型傳感器可以部署在密封容器中，以直接測(cè)量氧氣含量。IMP-PSt1 的測(cè)量范圍為 0 – 50 % 氧氣，檢測(cè)限為 0.05 % O2.
· 高空間分辨率 （< 50 μm）
· 高時(shí)間分辨率 （t90< 3 秒）
· 集成到定制外殼和設(shè)置中
· 無需耗氧
· 頂空和液體測(cè)量
