Start measurement Measurement of the oxygen content of sample dilution
and dilution water at the beginning of the incubation
period.
TDS Total dissolved solids
Temperature coefficient Value of the slope of a linear temperature function.
Temperature
compensation
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 probe or part of
a probe.
Test sample Designation of the 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.
TISAB English abbreviation for a sample conditioning solution,
which is used to adjust the ionic strength and pH value of
a sample.
Total Ionic Strength Adjustment Buffer
Total dissolved solids
(TDS)
Mass that remains of the substances dissolved in an
aqueous solution after a specified filtering and drying
procedure, as long as these substances are not volatile
under the conditions of this procedure.
