tiamo 2.4
Input 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).
Input 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 solution (TC conductivity) - %1.
Temperature coefficient
The temperature compensation is calculated on the basis of the value
entered (constant).
Input 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.
Selection DIN | Table entries
Default value DIN
