Specifications

Ratings: Maximum inlet pressure: 250 psig; Maximum working temperature: 160°F.
Pressure Drop: Minimum: 10 psi; Maximum: 100 psi.
Performance: (Based on 60 psig helium supply pressure at 50 psig outlet pressure)

Supply Rejection: 10 psi change in supply will not change outlet more than 0.07 psi.
Ambient Temperature Effect: (temperature coefficient)
Music wire - (60 psig range) 0.008 psi/°F
Ni-Span C° - (60 psig range) 0.004 psi/°F
Drift (Fairprene diaphragm): Less than 0.1% in first 15 minutes to a total of 0.2% long term.
(Stainless steel diaphagm): Less than 0.2% in first 15 minutes to a total of 0.8% long term.

Flow Regulation: From 1 SLPM to 20 SLPM, outlet pressure will not decrease by more then 1PSIG for unit with Fairprene diaphragm.
Baseline Oscillation: 0.0012 psi.
Precision Adjustment (resolution): 15 turns.

Regulating Range:
0 - 2.5 psig
0 - 5 psig
0 - 10 psig
0 - 30 psig
0 - 60 psig
0 - 100 psig

Connections:

1/8" NPT all ports on side.
