PVC Ion Gauge and Vacuum System Controller ● for passive UHV hot cathode ion gauges

The range of instruments comprises controllers for one or two passive hot cathode ion gauges as well as various plug-in modules for operation of additional passive Pirani sensors VSP521/VSP841 or active 0-10V vacuum transducers. Suitable hot cathode ion gauges and accessories like thermocouple temperature sensors for bake-out control or gauge cables are also available.
