Reference tempera-
ture
Fixed temperature value to compare temperature-dependent
measured values. For conductivity measurements, the measured
value is converted to a conductivity value at a reference temperature
of 20 °C or 25 °C.
Reset
Restoring the original condition of all settings of a measuring system.
Resistance
Short name for the specific electrolytic resistance. It corresponds to
the reciprocal value of the electrical conductivity.
Resolution
Smallest difference between two measured values that can be
displayed 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.
Stability control
Function to control the measured value stability.
Standard solution
The standard solution is a solution where the measured value is
known by definition. It is used to calibrate a measuring system.
Temperature coeffi-
cient
Value of the slope
of a linear temperature function.
Temperature compen-
sation
Name of a function that considers the temperature influence on the
measurement and converts it accordingly. Depending on the
measured parameter to be determined, the temperature
compensation functions in different ways. For conductimetric
measurements, the measured value is converted to a defined
reference temperature. For potentiometric measurements, the slope
value is adjusted to the temperature of the test sample but the
measured value is not converted.
Temperature function
Name of a mathematical function expressing the temperature
behavior of a test sample, a sensor or part of a sensor.
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.
