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 preparation of such cables.
No liability whatsoever will be accepted for damage arising from the improper connection of devices.
