Dissolved oxygen sensor solution

Complete monitoring solution including sensor, logger, connectivity and cloud.

The dissolved oxygen solution is built around the In-Situ RDO Blue optical dissolved oxygen sensor for reliable DO measurement in wastewater and water quality monitoring applications. The optical measurement principle eliminates the need for membranes and calibration, ensuring stable operation with minimal maintenance even under demanding field conditions.

All data is logged and transmitted automatically to the cloud, allowing operators to monitor water quality in real time and receive alarms if abnormal conditions occur.
