ANELVA M-832HG Ionization Gauge Controller Module

The ANELVA M-832HG Ionization Gauge Controller Module is a compact controller designed to operate ANELVA’s ionization vacuum gauges within a vacuum system, handling the control and readout of pressure measurements. It is part of Canon ANELVA’s HG controller family, with related models such as M-722HG, M-822HG, and M-922HG, and it’s also available in a CC-Link compatible variant (M-832HG-CC) for networked control. The model is listed as discontinued by the manufacturer, yet it remains visible in used-equipment listings and CC-Link catalogs, reflecting its persisted presence in legacy installations and refurbishment markets. Verified specifications indicate a measurement range of 1.3×10^-7 Pa to 13 Pa, enabling operation from high vacuum toward near-atmospheric pressures in appropriate vacuum applications. In practice, buyers commonly encounter the M-832HG in secondary markets and catalog listings, where it is traded alongside other ANELVA gauge controllers as a legacy component with known compatibility requirements for existing vacuum systems.
