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).
