Dissolved oxygen meters

Oxygen meters are devices that use the amount of oxygen that is dissolved in or carried in a fluid, i.e. a multi-capacity instrument for water quality inspection. Typically, these devices use two measurement scales: parts per million (ppm) or saturation percentage (%). Dissolved oxygen meters are used in the field and in laboratories.

This equipment is used to measure and control the oxygen content in the various points of the water circuit of steam boiler installations, in order to avoid corrosion of metals caused by the oxidizing power of oxygen. Among other uses, there is the care of aquatic ecosystems and more, since one of its most important applications is fish farming, where the level of oxygen must be continuously controlled to achieve optimal reproduction and avoid mortality of fish caused by low oxygen levels.
