2、 Digital Fluorescent Dissolved Oxygen Sensor

SY-ID-400The measurement of digital dissolved oxygen sensor adopts the principle of optical fluorescence method. The fluorescent substance at the front end of the sensor is a special platinum metalloporphyrin composite polyester foil that allows gas to pass through. The surface is coated with a black light blocking material to avoid exposure and interference from other fluorescent substances in water.

No oxygen consumption, no requirements for flow rate and agitation, no interference from chemical substances such as sulfides, higher resolution and measurement accuracy, low maintenance.
