Product Q&A

Q:What is the measurement principle of this sensor?

It uses fluorescence measurement where blue light excites a phosphor layer to emit red light, which is inversely proportional to oxygen concentration.

Q:What is the measuring range for dissolved oxygen?

The range is 0-20 mg/L or 0-20 ppm, with a resolution of 0.1 mg/L.

Q:Is the sensor suitable for seawater applications?

Yes, a titanium version is available specifically for seawater applications, while the standard body is SUS316L + PVC.

Q:What is the response time of the sensor?

The response time is less than 60 seconds to reach 90% of the right value.

Q:Does the sensor require frequent maintenance?

No, the new oxygen-sensitive film ensures high stability and requires virtually no maintenance.
