Optical Dissolved Oxygen Sensor, OPTOD
The OPTOD is based on luminescent optical technology. The OPTOD sensor is approved by the ASTM International Method D888-05. 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 an accurate measure in all situations, and especially in very low oxygen concentrations. The OPTOD sensor stores calibration and history data within the sensor, allowing a "plug and play" system without re-calibration. Used in urban wastewater treatment, industrial effluent treatment, surface water monitoring, sea water monitoring, fish farming, etc.
