The "high concentration" mea-
suring cell
The measuring cell has the same function as the "sensitive" measuring cell, but has a
higher electrolyte volume. It is suitable for a chlorine content of 10 to 1000 µg
, and is
recommended in particular for TX determination of highly contaminated waste and of
polymer samples with high PVC content.
Here, as well, the maintenance-free combined electrode is used.
