The ABB C1901 circular chart recorder is a single pen, fully programmable circular chart recorder. The instrument's straightforward operator controls and robust construction make it suitable for a variety of industrial environments.

NEMA 4X protection ensures that the ABB C1901 can survive in the harshest environments; it is ideal for use in panels which are regularly hosed down. The tough, acid-resistant case and secure cable-entry glands maintain the NEMA 4X rating for wall-mount or pipe-mount instruments.

A choice of mounting options enables simple installation of ABB C1901 circular chart recorders in a panel, on a wall or on a pipe. Mains isolation can be provided by an optional power switch within the instrument.
