具有自我清洗和自我验证功能的在线荧光法溶解氧分析仪提供了更高的可靠性和无与伦比的低维护率。光学DO计已经很大程度上取代了电化学DO传感器,因为它们具有更好的可靠性和更低的维护要求。

OxySense系列DO传感器可与不同的控制器兼容,为您提供不同的通信、显示和控制选项。

The sensing element (lumiphore) is activated, or excited when illuminated with a blue light. When activated, the lumiphore then emits red light with an intensity that is inversely proportional to the amount of oxygen dissolved in the water.

There is also a time delay between the peak emission of blue light and peak response of fluoresced red light. The amount of delay is inversely proportional to the amount of oxygen present. This time delay can be expressed as a phase shift between the wave patterns of incident blue light and the fluoresced red light. This is in turn reported by the electronics as a ppm or mg/l reading of Dissolved Oxygen. The advantages of this technology are that it is more stable than traditional electrochemical devices and far more resistant to abrasion. By using the state of the art sensor and electronics together the reliability, accuracy, and flexibility of the OxySense Online Optical DO analyser is far superior to that of its competitors.
