Description
Optical Technology without calibration
Oxygen Optical Digital Sensor
Oxygen Optical Digital Sensor 7m OPTOD for ODEON
Fischer connector for ODEON (handheld multiparameter device) and Module 4200 (USB – RS485 converter).
The OPTOD (Optical Dissolved Oxygen technology) is based on luminescent optical technology. The OPTOD sensor is approved by the ASTM International Method D888-05 and by the International norm ISO 17289.
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 situations and especially in very low oxygen concentrations
Advantages
- Optical Technology without calibration
- Digital Technology (Modbus RS-485)
- No drift, Reduced maintenance
- Body in Stainless steel (316 L) or Titanium

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…).
Mechanic
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.
- Urban wastewater treatment
- Industrial effluent treatment
- Surface water monitoring,
- Sea water monitoring
- Fish farming
- Aquarium
- Drinking water
