Connecting cables to external devices must have an
appropriate 25-pin connector (male). Metrohm offers
connector sockets (K.210.9060) and the associated
housing (K.210.0002) as an option for the prepara-
tion of such cables.
No liability whatsoever will be accepted for damage arising from improper connection of devices.
