Measuring cell
The measuring cell is equipped with electrodes for generation and indication. The elec-
trodes are color-coded:
¡ Generation: Yellow anode, red cathode
¡ Indication: Black indicator electrodes
The measuring gas is routed into the measuring cell via the gas inlet tube. The solution
for the end point routine, the sodium sulfate solution (Na
2
SO
3
) and the solutions for the
cell measurements are dosed, for example, via the port for manual dosing.
The measuring cell must be filled with approx. 100ml electrolyte solution (approx. to
the height of the manual dosing port).
