OPTOD : OPTICAL DISSOLVED OXYGEN

APPLICATIONS

  • Urban waste water 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 SE OPTOD can be connected to all devices commonly used (Datalogger, Controller, Automat, Remote System…).
