Oxygen saturation
Short name for "Relative D.O. saturation".
pH value
The pH value is a measure of the acidic or basic effect of an aqueous
solution. It corresponds to the negative decadic logarithm of the molal
hydrogen ions activity divided by the unit of the molality. The practical
pH value is the value of a pH measurement.
Potentiometry
Name of a measuring technique. The signal (depending on the mea-
sured parameter) of the electrode is the electrical potential. The elec-
trical current remains constant.
Reset
Restoring the original condition of all settings of a measuring system.
Resolution
Smallest difference between two measured values that can be dis-
played by a meter.
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
monitoring. 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.
