Dissolved oxygen sensor OPTOD

Urban wastewater treatment • Industrial effluent treatment • Surface water monitoring, • Sea water monitoring, fish farming, aquarium • Drinking water OPTICAL TECHNOLOGY 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 requirements 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 DIGITAL TECHNOLOGY The “smart” OPTOD sensor stores calibration and history data within the sensor. This allows you a “plug and play” system without re-calibration. Thanks to the Universal Modbus RS485 protocol, the PONSEL OPTOD can be connected to all devices commonly used (Datalogger, Controller, Automat, Remote System…). MECANIC Compact, strong and light, the sensor allows a portable or in fixed/permanent use. Body in Stainless steel 316 L (passivation treatment) or in Titanium for applications in corrosive environment. • Optical Technology without calibration • Digital Technology (Modbus RS-485) • No drift, Reduced maintenance • Body in Stainless steel (316 L) or Titanium TECHNICAL CHARACTERISTICS Measures Measure principle Optical measure by luminescence Measure ranges 0,00 to 20,00 mg/L 0,00 to 20,00 ppm 0-200% Resolution 0,01 Accuracy +/- 0,1mg/L +/- 0,1 ppm +/- 1 % Response time 90% of the value in less than 60 seconds Frequency of recommended measure >5 s Water move No necessary move
