Temperature compensa-
tion for concentrated
solutions
For the measurement of aqueous solutions
z in a wide concentration range
z in a wide temperature range (|T - Tref| > 10 K)
z with freely adjustable reference temperature,
procedures with an individually determined nonlinear temperature
compensation are suitable (designation: TC nLin1 ... 4).
The temperature compensation procedures have different ways of
determining the temperature and concentration dependency.
Procedure Determining the temperature dependency
(and concentration dependency)
TC nLin1 Temperature coefficients (e.g. from further reading)
can be selected and entered manually.
TC nLin2 z with one standard
of known concentration
z at different temperatures
TC nLin3 z with several standards
of known concentration
z at different temperatures
TC nLin4 z with several standards
of unknown concentration
(prepared with equidistant dilution)
z at different temperatures
