A short hose with a T piece can be found in the accessories of the measuring cell. The
hose and the T piece are applied to the adapter and connected to the exhaust hose. One
side of the T piece remains open. The acetic acid vapors can be drawn out of the detec-
tion module effectively without the electrolyte solution evaporating too rapidly.
