REFERENCE STANDARD
In designing the instrument, the reference taken for measuring Oxygen dissolved in water, using an
electrochemical probe method, was standard UNI EN 25814 (Water quality. Determination of dis-
solved oxygen. Electrochemical probe method).
The German standard DIN 30408 part 23 was also considered (German standard methods for the
examination of water, waste water and sludge. Gaseous constituents group G: Determination of
oxygen saturation index), which provides similar data to the European standard with reference to
the saturated concentration of oxygen in pure water.
