E-mail: info@supmea.com SUP-DY2900 Dissolved oxygen online analyzer, an intelligent online chemical analyzer. The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, so the concentration of oxygen molecules is calculated. Features ■ Support dissolved oxygen(DO), saturation(SAT),oxygen partial pressure(OPP) and temperature measure. ■ Support...

E-mail: info@supmea.com ■ Sensor design: – Oxygen-sensitive molecules (markers) are integrated in an optically active layer (fluorescence layer). – The surface of the fluorescence layer is in contact with the medium. – The sensor optics are directed at the underside of the fluorescence layer. ■ There is an equilibrium between the oxygen partial pressure in the medium and that in the fluorescence layer: – If the sensor is immersed in the medium, the equilibrium is established very quickly. ■ Measuring process: – The sensor optics send green light pulses to the fluorescence layer. – The...
