ODO-210 荧光溶解氧传感器采用“动态荧光淬灭”原理来测量水中溶解。

The Aquistar® Dissolved Oxygen (DO) sensor represents the next generation in trouble-free oxygen-sensing design. Utilizing fluorescence of a stable, immobilized ruthenium-based film matrix, the sensor employs precision optical transmission and detection to measure oxygen concentration in the fluid outside of the sensor. Measurement is based on photons of light responding to oxygen outside of the sensor, rather than what passes through a sensor membrane. This design eliminates the need to compensate (calibrate) for changes in membrane permeability due to fouling or make up for oxygen consumption by the sensor itself (which required water movement or flow). Unlike alternative optical designs (such as those based on luminescence), this sensor does not have a consumable component; this fluorescence design negates the need to replace photo-bleached caps.","The DO Sensor connects topside to a GDL Control Box, which includes a 12 VDC power supply that powers both the control box and the sensor. The control box has a communications port for connecting to a computer running INW's free Aqua4Plus control software. This easy-to-use program allows you to view the sensor status, monitor real time data, create flexible and powerful test sequences, as well as display data in tabular or graphic format and export to spreadsheets and databases.","This sensor is fast, accurate, and precise to very low oxygen levels (0.01 ppm) and is the right technology for the demands of down-hole groundwater and surface water environmental monitoring.","Features

蛙视新一代溶解氧传感器，基于荧光猝熄原理，蓝光照射到荧光 氧分子探针上激发出红光，由于氧分子是荧光探针的猝熄剂，氧 分子可带走能量，所以激发出的红光的时间和强度与氧分子的浓 度成反比。溶解氧传感器通过测量受激发的红光和参比光的相位 差，并结合温度补偿后的 3D 标定数据模型，计算出氧分子浓度
