(55850-678):
Regulators have a stainless steel barstock body and are suitable for corrosive gas applications, high-purity gas applications, research sample systems, process analyzers, gas chromatography, EPA protocol mixes, laser gas systems, and emission monitoring systems. The two-stage design provides constant outlet pressure regardless of change in cylinder pressure. They may be used with corrosive gas applications. A stainless steel diaphragm eliminates contamination from diffusion or outgassing. A one-piece PTFE encapsulated seat design includes a sintered filter to protect the seat from particulate contamination. The 1x10-9cc/sec. inboard helium leak rate maintains gas purity levels. Front panel mountable.
