Salinity
The absolute salinity S
A
of seawater corresponds to the relationship
of the mass of dissolved salts to the mass of the solution (in g/Kg). In
practice, this dimension cannot be measured directly. Therefore, the
practical salinity according to IOT is used for oceanographic monitor-
ing. It is determined by measuring the electrical conductivity.
Salt content
General designation for the quantity of salt dissolved in water.
Slope
The slope of a linear calibration function.
Stability control
(AutoRead )
Function to control the measured value stability.
Standard solution
The standard solution is a solution where the measured value is
known.
It is used to calibrate a measuring system.
Test sample
Designation of the test sample ready to be measured. Normally, a test
sample is made by processing the original sample. The test sample
and original sample are identical if the test sample was not processed.
Zero point
The zero point of a pH combination electrode is the pH value at which
the electromotive force of the pH combination electrode at a specified
temperature is zero. Normally, this is at 25 °C.
