Digital Optical Dissolved Oxygen Sensor Luminescence Measure For Fish Farming
The optical dissolved oxygen sensor OPTOD uses optical dissolved oxygen technology, which is based on luminescent optical technology. The OPTOD sensor is approved by the ASTM International Method D888-05.
Application Of The Optical Dissolved Oxygen Sensor
Aquarium
Drinking water
Advantages of The Optical Dissolved Oxygen Sensor
Meet the demands of field works and short or long term campaigns
"plug and play" system without re-calibration
Optical Technology without calibration
No drift, Reduced maintenance
Accurate measure in all situation and especially in very low oxygen concentrations
Digital communication Modbus RS485 protocol
Can be connected to all devices commonly used
Compact, strong, and light, the sensor allows portable or fixed/permanent use
Body in Stainless steel (316 L) or Titanium for applications in corrosive environment.
