The optical dissolved oxygen sensor does not require calibration it features ultra-low power technology, the Optical Dissolved Oxygen sensor meets the demands of field work and short or long term water quality monitoring campaigns.
The Optical Dissolved Oxygen Technology is based on luminescent optical technology. The OPTOD sensor is approved by the ASTM International Method D888-05.
Without oxygen consumption, this technology allows you an accurate measure in all situations and especially in very low concentrations.
The “smart” OPTOD sensor stores calibration and history data within the sensor. This provides a plug-and-play system without re-calibration.
Thanks to the Universal Modbus RS485 protocol, the Ponsel digital C4E sensor can be connected to all devices commonly used (Datalogger, Controllers).
