Açıklama

Conventional regulators exhibit significant deviation from setpoint when pressure and temperature effects are introduced to the carrier gas stream. Parker Precision Fluidics new Model 8320 Regulator controls these effects to within ±0.50 PSIG, significantly reducing system testing and field commissioning cycle time. 8320 is an excellent drop-in replacement choice for obsolete carrier gas regulators.

Typical Applications

Process Gas Chromatography — Helium or Hydrogen Carrier Gas
Environmental Analyzers

Features
