Multi-Gauge

The Varian Multi-Gauge is the leader in modular vacuum gauge controllers. Contained within its compact, half-rack, 3^1/2 inch height is the capability to operate simultaneously up to thirteen vacuum transducers, conserving expensive and scarce electronic rack space. Multi-Gauge can operate standard or UHV Bayard- Alpert gauges, cold cathode gauges, thermocouples, and ConvecTorr gauge tubes, as well as capacitance manometers. With the widest selection of transducer technology available in any vacuum gauge controller, a Multi-Gauge can be configured for your exact system requirement.
