Dissolved oxygen (DO) is one of the most important parameters monitored when evaluating water quality, aquatic biology, and other environmental and industrial processes. The In-Situ Rugged Dissolved Oxygen (RDO^®) Probe measures DO using the latest advancements in optical measurement technology. Water quality professionals will benefit from In-Situ Inc.’s investment in new product development. By improving upon the breakthrough optical DO sensor technology that In-Situ Inc. first brought to the environmental market in early 2004, our latest generation of RDO Probes provides higher quality data and more robust performance at a significantly lower cost than currently available optical DO probes.

Comparison of DO Methods

The Alliance for Coastal Technologies (ACT) conducts field tests that compare different technologies. In 2004, ACT tested galvanic, polarographic, and optical probes in field conditions. The following table compares DO measurement technologies and was published in the ACT Workshop Proceedings, January 2004 (State of Technology in the Development and Application of Dissolved Oxygen Sensors, University of Maryland Technical Report Series No. TS-444-04-CBL, p. 11).
