Where to buy

The sensor is based on optical fluorescence lifetime quenching technique. Its technical procedure meets ASTM D888-09 standard for optical sensing of dissolved oxygen. This online sensor is developed to integrate with Yosemite wireless monitoring system. Its rugged design and large measurement range make it ideal for sampling, flow cell, ground water and waste water measurements.

Applications

Fish farmer, waste water plant, river, stream, and ocean monitoring

Measurement Principle

The dissolved oxygen sensor measurement is based on well-known oxygen fluorescence quenching technology. When oxygen sensing membrane film is excited by blue LED excitation light, the sensing film will emit red emission light. The phase delay between blue excitation and red emission is a function of oxygen concentration present. By measuring the phase delay the dissolved oxygen concentration can be calculated.

Advantages of optical dissolved oxygen measurement

·         Easy use, no membrane, no electrolyte.

·         Long lifetime, maintenance free and less calibration.

·         No flow dependency and fast response.

·         Immune to electrical interference,  no chemical interference.
