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 µ 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:
Temperature Conductivity
18 °C 127 µ S/cm
19 °C 130 µ S/cm
20 °C 133 µ S/cm
21 °C 136 µ S/cm
22 °C 138 µ S/cm
23 °C 141 µ S/cm
24 °C 144 µ S/cm
25 °C 147 µ S/cm
Starts the automatic determination of the cell
constants. When the determination has ended
the Enter/check cell constants window appears in
which the automatically determined cell con-
stants have been entered:
