Reference
temperature
In order to compare values measured at different temperatures, the values
have to be converted to a fixed temperature. This temperature is 25 °C, or,
as an exception, 20 °C.
Reset Restoring the original condition of all settings of a measuring system.
Resistance All substances (solids, liquids, or gases) with mobile charge carriers, like for
example electrons or ions, have a finite ohmic resistance, which means they
have an electric conductance or an electric conductivity that can be
measured.
Resolution Smallest difference between two measured values that can be displayed by
a meter.
Salinity The salinity is a sum parameter especially for seawater.
It quotes the salt content.
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
compensation (TC)
The temperature has a very strong impact on the electrical conductivity. To
be able to compare measured values, it is necessary to temper or convert
the test sample to a reference temperature.
Total dissolved
solids (TDS)
Mass that remains of the substances dissolved in an aqueous solution after
a fixed filtering and drying procedure, as far as these substances are not
volatile under the conditions of this procedure. The total dissolved solids
refer to the volume of the filtered aqueous sample used and are given in
mg/l.
