XIX. TEMPERATURE COMPENSATION (Tempco)
of Aqueous Solutions
Electrical conductivity indicates solution concentration and ionization
of the dissolved material. Since temperature greatly affects ionization,
conductivity measurements are temperature dependent and are normally
corrected to read what they would be at 25°C.
A. Standardized to 25°C
Conductivity is very accurately measured in the P
ool
P
ro
by a method
that ignores fill level, electrolysis, electrode characteristics, etc., and
uses a microprocessor to perform temperature compensation. In simpler
instruments, conductivity values are usually assigned an average
correction similar to that of KCl solutions for correction to 25°C. The
correction to an equivalent KCl solution is a standard set by chemists that
standardizes the measurements and allows calibration with precise KCl
solutions. In the P
ool
P
ro
, this correction can be set to other solutions or
tailored for special measurements or applications.
B. Tempco Variation
Most conductivity instruments use an approximation of the temperature
characteristics of solutions, perhaps even assuming a constant value.
The value for KCl is often quoted simply as 2%/°C. In fact, KCl tempco
