Dissolved Oxygen Sensor
- Optical Technology without calibration
- Digital Technology (Modbus RS-485)
- No drift, Reduced maintenance
- Robust, for field application
The OPTOD (Optical Dissolved Oxygen technology) is based on luminescent optical technology. The OPTOD sensor is approved by the ASTM International Method D888-05.
Without calibration requirments and thanks to an ultra low power technology, the OPTOD sensor meets the demands of field works and short or long term campaigns.
Without oxygen consumption, this technology allows you an accurate measure in all situation and especially in very low oxygen concentrations
