Optical Dissolved Oxygen Sensor, OPTOD
Type:  Sensor
Description:  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.
Connectivity:  Modbus
Features:  Optical Technology without calibration; Digital Technology (Modbus RS-485); No drift, Reduced maintenance; Body in Stainless steel (316 L) or Titanium
