You roll up on a pond covered with garish green algae, and wonder if any animal could live in there. Instead of a lengthy fishing expedition and possibly dredging the pond*, you decide to measure the first parameter that can tell you how hospitable it would be to animal life: dissolved oxygen. This parameter implicitly tells you how much nutrient overloading (i.e. from fertilizer dissolved in runoff) a particular body of water is suffering from, and is critical for preserving good habitats for fish, macroscopic invertebrates, mollusks, etc.

The dissolved oxygen module board connects with a dissolved oxygen probe by way of a SMC connector. This probe is rated for full immersion up to the end of the cable, and can operate over a broad range of temperatures. Dissolved oxygen calibration standard solutions not included.


  • Dissolved oxygen (DO) [mg/L]

*We do not condone the indiscriminate dredging of algae-choked ponds, nor the indiscriminate over-fertilizing of fields, yards, and golf courses.
