HVG-2020B Piezo-Pirani Vacuum Gauge Get a Quote

The HVG-2020B vacuum gauge features two sensors, a piezo-based transducer and a thermal based Pirani sensor, in a single, small package. The piezo is used at higher pressures, above 20 Torr, to accurately measure pressures. This sensor is media-isolated and is also gas composition independent. The Pirani sensor is a precision welded hot-wire thermal sensor that measures pressures below 1 Torr.
