APPENDICES
T2 should be selected as a typical sample temperature and
should be approximately 10°C different from T1. The
temperature coefficients of the following electrolytes
generally fall into the ranges show below:
Acids: 1.0 - 1.6%/°C
Bases: 1.8 - 2.2%/°C
Salts: 2.2 - 3.0%/°C
Drinking water: 2.0%/°C
Ultra-pure water: 5.2%/°C
Average temperature coefficients of standard electrolyte
solutions expressed as %/°C of the conductivity value at
25°C.
