Block A
Channel 1...4
Each channel
of Block A for which the cell con-
stant of the conductivity cell is to be determined
can be marked.
Block B
Channel 1...4
Each channel
of Block B for which the cell con-
stant of the conductivity cell is to be determined
can be marked.
Conductivity of standard solution
Conductivity of the standard solution in

S/cm
which is filled into all measuring vessels for
which the cell constant of the conductivity cell
is to be determined.
A solution of c(KCL) = 1 mmol/L, prepared
from the 6.2301.060 Conductivity standard (KCl
0.1 mol/L) available as an option, can be used
as standard solution. The conductivity of this
standard solution is:
