  • Wide diaphragm design for precise flow control even as the cylinder pressure changes
  • Finer graduations for precise reading of cylinder contents
  • Stainless steel gauge
  • All wetted surfaces have proprietary passivated coating to ensure non-reaction with calibration gas
  • Wide choice of outlets and inlets available
  • Side outlet prevents tubing from kinking

Flow Matching Regulator

Flow Matching Regulator

PortaGas demonstrates a commitment to calibration innovation for the Environmental and Industrial Hygiene markets by being the first to develop a Flow Matching Regulator. Designed for instruments with sample draw pumps, the Flow Matching Regulator is an excellent solution to overcome the inconveniences of using sample bags or inefficient T-assemblies. The Flow Matching Regulator also provides excellent repeatability of sensor response to the calibration gas opposed to sampling bags.

  • When flow is matched ball will float in green zone
  • Patent pending design
