Pro-Oceanus: Solu-Blu™ Total Dissolved Gas Pressure Probe

Durable and accurate dissolved gas pressure sensor. Ideal for gas saturation measurements in RAS and hydroelectic dams.

The Solu-Blu™ Series of instruments combine rugged design, ease of use and versatility, all in a single sensor package. The measurement of a gas dissolved in a liquid is facilitated by a semi-permeable membrane that allows gases to transfer from water into a gas head space where the measurement is made.

The Solu-Blu™ total dissolved gas, TDG, probe can be used for long-term continuous in-situ monitoring to provide reliable dissolved gas pressure measurements. It provides accurate TDG pressure data and is designed for use in aquaculture, dam spillways, groundwater monitoring, and industrial applications.

Unlike other total gas pressure probes, the Solu-Blu™ TDG is not affected by increasing hydrostatic pressure. It can be used in a range of liquids ranging from fresh- and salt-water to industrial fluids such as oil or hydraulic fluid.

The Solu-Blu™ TDG probe is designed for long-term deployments with simple, stable and accurate results.
