BetaGauge 311
Pressure calibrator.
BetaGauge 311 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).
