This Granville-Phillips / Helix Technologies 20352001 vacuum gauge controller is part of the 352 gauge controller family used for vacuum pressure monitoring in semiconductor, thin-film, research, and industrial vacuum systems. The 352 series is documented as supporting operation of one Stabil-Ion gauge and up to three Convectron gauges, with pressure readout via DeviceNet on supported configurations, making it useful for legacy vacuum tools, process systems, and replacement controller applications. This unit is best suited for users maintaining existing Granville-Phillips/Helix vacuum hardware, especially systems where matching the controller part number and interface configuration is important. Buyers should verify gauge compatibility, power/input requirements, interface type, cabling, and any OEM configuration labels before purchase.
