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 materials are used for the sensor body?

The body is made of SUS316L + PVC (limited edition) or titanium for seawater versions.

Q:Does the sensor require frequent maintenance?

No, it uses a new oxygen-sensitive film and breakthrough fluorescence techniques that require virtually no maintenance.

Q:What is the output interface of the sensor?

The sensor provides MODBUS RS485 output for data transmission.

Q:Is the sensor suitable for seawater applications?

Yes, a titanium version is available specifically for seawater applications.
