Measuring principle:Optical oxygen measurement

Application:Aeration tank, river monitoring, water treatment, fish farming.

Characteristic:Digital, optical (luminescence) dissolved oxygen measurement.No flow needed - measurement possible in still water.

Measurement range:0mg/l ... 20mg/l；0%SAT ... 200%SAT；0 ... 400hPa

Measuring principle:Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.

Design:Calibration data saved in sensor.High degree of EMC protection.
