With the aid of a Metrohm 731 Relay Box the output leads of the 711 Liquino
can be monitored and, according to their line conditions, two low-voltage
d.c. voltage outputs and two mains voltage outputs can be switched.
In this way the heating bath can be switched automatically via the tempera-
ture monitoring function. If the measured temperature falls below a certain
value the bath is heated up.
A connected pump (e.g. the Metrohm 772 Pump Unit) can be selectively
switched on or off during the method procedure.
