The 500 Series regulators, characterized by their single-stage, piston-style design, are engineered for the precise administration of non-reactive and mildly reactive gas mixtures (under 100 PPM)*. These devices are specifically suited for use with disposable cylinders of 58 liters and 103 liters, equipped with a 5/8”-18 UNF (C-10) inlet connection.

*It is noted that mildly reactive gases can interact over time with the brass internal components of the 500 Series regulators. To preserve calibration precision, it is advised to disconnect the regulator from its cylinder following every use. For those requiring sustained operation with reactive gases, the 6000 Series regulator from NorLab is advised.

Key Features include:

• Preset Flow Rate: 0.25 LPM of air
• Peak Inlet Pressure Tolerance: Up to 1000 PSIG
• Connection for Inlet: 5/8”-18 UNF (C-10)
• Connection for Outlet: 3/16” hose barb
• Temperature Range for Operation: Between 0°F and 140°F
