Technical note

As is clear from equation ② , when a conductivity cell having a cell constant "J" of 1 m
-1
is used (in other words, when a conductivity cell having two pole plates that each have
an area "a" of 1 m
2
and are positioned parallel to each other such that the distance "l"
between the two plates is 1 m is used) the inverse of the resistance "R" of the solution
between both pole plates is the conductivity. Conductivity is defined in this way, but it
changes according to the temperature of the solution. The conductivity of a solution is
generally expressed as the value when the solution is 25°C.
