Range -20.0 ... 150.0 °C
Default value 20.0 °C
Reference temperature
The electrical conductivity depends greatly on the temperature. The con-
ductivity measured at a particular temperature is thus automatically con-
verted to this reference temperature (usually 20 °C or 25 °C).
Range -20.0 ... 150.0 °C
Default value 20.0 °C
Selection off
off
The conductivity at the measuring temperature is displayed.
Temperature compensation
Definition of the type how the temperature compensation is to be carried
out.
Selection Temperature coefficient | Sample solution
Default value Temperature coefficient
Temperature coefficient
Manual entry of a constant temperature coefficient.
Sample solution
Selection of a function for the temperature coefficient from the table
Sample solutions (TC conductivity).
Temperature coefficient
The temperature compensation is calculated on the basis of the value
entered (constant).
Range 0.00 ... 9.99 %/°C
Default value 2.00 %/°C
Sample solution
The temperature compensation is carried out on the basis of temperature-
dependent coefficients and should be used for determinations where the
sample temperature is not constant. There are two possibilities:
￭ It is possible to use a sample solution whose temperature coefficient
has been determined by a previous measurement (MEAS TC Cond).
￭ For ground water, spring water and surface water, the temperature
coefficients according to standard ISO 7888:1985 (German version:
DIN EN 27888:1993) are stored in the system.
