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.FeaturesDigital sensor,Modbus RS485 interfaceNo membrane, no electrolyte, easy sensing cap replacementNo oxygen consumption, no flow dependency, no H2S interferenceEmbedded temperature for automatic temperature compensationSpecificationsMeasurement Range0~20mg/L or ~200% SATAccuracy1% or 0.1 mg/LResponse time20 secSensor Drifting
