Duplex and Differential Pressure Gauges

Duplex and differential pressure gauges are suitable for the measurement of positive and negative overpressures between 0-2.5 mbar and 0-600 bar for gaseous and liquid media that do not corrode brass/bronze or stainless steel. For some versions of the duplex and differential pressure gauges an installation of additional electrical accessory and/or chemical seals is possible, as well as an increased protection against overpressure.
