Online Optical Dissolved Oxygen Sensor

The DO sensor is based on well known oxygen fluorescence lifetime quenching technique. Its technical procedure meets ASTM D888-09 standard for optical sensing of dissolved oxygen. Its rugged design and
large measurement range make it an ideal solution for water quality measurement on streams, rivers, lakes, estuaries, and coastal waters.
