The 311 is a high accuracy pressure calibrator with special features intended to facilitate calibration of mass flow computers. With one internal pressure range and an available adapter for external BetaPort-P pressure modules, the possibilities are extensive. In addition, the advanced pressure calibrator has a port to connect a precision RTD probe for the temperature factor calibration required for electronic flow meters (EFMs).
