Description

The OPTOD (Optical Dissolved Oxygen Technology) sensor is based on luminescent optical technology. The OPTOD is offered with ASTM International Method D888-05 approval. Without regular calibration requirements and ultra-low power technology, the OPTOD sensor meets the demands of field works, and is suited to both short and long term campaigns. Without consuming oxygen during measurement, the technology allows you an accurate measure in all situation and especially in very low oxygen concentrations. This sensor can be purchased in either stainless steel or titanium to suite site requirements and reduce corression in caustic waters.

The Smart OPTOD sensor stores all calibration history within the sensor. This allows the sensor to be interchanged between different systems without losing accuracy. Thanks to the sensors Universal Modbus RS 485 and SDI-12 communications the sensor can easily be connected directly to system incorporating this communication such as LoRaWAN, PLC, SCADA systems, telemetry and data logging systems.

The Aqualabo optical dissolved oxygen sensor delivers reliable DO measurements over a long operating life. There are no membranes to replace, no electrolyte solutions to replenish, and no anodes to clean. Maintaining the sensor is as easy as replacing the optical sensing cap once every 1-2 years, and since all calibration data is stored on the cap, there’s no need to calibrate.

The sensor also has the option of being attached to a 3 metre, 7 metre or 15 metre cable.
