INFICON Pirani vacuum gauge PGE300 Atmospheric pressure to medium vacuum gauge
The INFICON Pirani Gauge Enhanced 300 (PGE300) is equipped with the latest digital convection enhanced Pirani technology on the market, just like the larger brotherP GE500. PGE300 is equipped with the same sensor components as PGE500 to obtain equally high accuracy readings in the measurement range of 100 to 1000 mbar. PGE300 only provides the key built-in features that most users in the vacuum industry pursue to minimize costs and improve efficiency. This robust instrument and sensor design, combined with the factory’s built-in clear reading LED display, three optional analog output signals, and set point relays, makes PGE300 a high-value/low-cost option for all customers, not just OEM customers. These characteristics make the instrument suitable for numerous economical vacuum measurement applications that require a range of low to high vacuum degrees. Due to its wider measurement range and higher accuracy (especially under low pressure conditions), as well as its affordable built-in features, PGE300 is also the preferred active vacuum gauge when replacing thermocouple instruments in vacuum systems.
