More About this Item

The BetaGauge 321/311 is a general purpose, high accuracy pressure calibrator with special features intended to facilitate calibration of mass flow computers. With one or two internal pressure ranges and an available adapter for external BetaPort–P pressure modules, the possibilities are extensive. In addition, it has a port to connect a precision RTD probe for the temperature factor calibration required for electronic flowmeters (EFMs).

  • Ranges: (in PSI) 0.3, 1, 5, 15, 30, 100, 300, 500, 1000, 1500, 3000, 5000 and 10000
  • One (311) or two (321) isolated, stainless steel pressure sensors
  • Temperature compensation to ensure field use accuracy
  • External pressure module connection supports all BetaPort-P
  • pressure modules (25+ ranges) using optional BPPA-100 Pressure
