specs 
The LMSS regulators are designed and constructed for both high purity and general purpose applications. While compact in design these regulators provided outstanding performance, but are rugged and versatile enough for laboratory or plant applications. They are ideally suited for use for applications where precise control of pressure is required.
FEATURES
- Minimal internal volume: .450 cubic inches.
- Seat area protected by a 30 micron filter.
- Four delivery pressure ranges available.
- Stainless steel diaphragm eliminates contamination from diffusion or out gassing.
- External self reseating relief valve.
- Designed to pass an helium leak-rate test of 1x10-8 SCC/SEC.
APPLICATIONS
The LMSS series regulators are ideal for critical pressure reduction applications, where precise control of pressure or flow is required. They are an excellent choice for use with high purity carrier gases or gas mixtures used with gas chromatographs and other instrumentation requiring up to 5.0 gas purity.
