Aanderaa, a Xylem Brand products

Salt Water Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring water conductivity. Measuring conductivity of salt water is a key parameter for in-situ measurements of several fundamental physical properties of water.

The Aanderaa Oxygen Sensor was the first and only to measure dissolved oxygen for years without drift  - now it is one of the fastest! Below you can read more about the oxygen sensor working principle. Since oxygen is involved in most of the biological and chemical processes in aquatic environments, it is a crucial parameter to measure. Oxygen can also be used as a tracer in oceanographic studies. Aanderaa revolutionized oceanographic oxygen monitoring/research with the introduction of oxygen Sensor in 2002. Applications range from shallow creeks to the deepest trenches, from tropical to in-ice/in-sediment measurements. More than 150 scientific papers have so far been published using these optodes, including publications on the oxygen sensor working principle. The oxygen sensor is designed to measure absolute oxygen concentration and % saturation. The sensor can be used from streams to deep sea, from fish farms to waste water and from polar ice areas to hydrothermal vents.
