APPENDIX B:

Temperature Effect

Conductivity measurements are

temperature dependent; if the temperature

increases, conductivity increases. For

example, the conductivity measured in a

0.01 M KCl solution at 20°C is 1.273 mS/

cm, whereas at 25°C, it is 1.409 mS/cm.

The concept of reference temperature

(normalization temperature) was

introduced to allow the comparison

of conductivity results obtained at

different temperatures. The reference

temperature is usually 20°C or 25°C. The

pen measures the actual conductivity

and temperature, then converts it

to the reference temperature using

a temperature correction function

and displays the conductivity at the

reference temperature. It is mandatory to

associate the temperature together with

a conductivity result. If no temperature

correction is applied, the conductivity
