Optical Dissolved Oxygen Sensor with temperature

Full Description

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 work and short or long term campaigns. 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. The sensor includes built-in Modbus RS485 and SDI-12 outputs.
