BetaGauge 311A Pressure Calibrator

The BetaGauge 311A Pressure calibrator is a general purpose, 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).
