58L/103L Regulator

The MESA Series 500 fixed flow calibration gas regulator is a single stage piston style flow regulator. The control valve permits constant calibration gas flow and easy on/off. The series 500 regulator is for use with MESA's 58L and 103L disposable calibration gas cylinders. The brass regulators are recommended for non-corrosive calibration gas service. For reactive calibration gas standards, use the 500 Series regulator in stainless steel. The stainless steel version is available in 0.50 and 1.00 liter per minute flow rates. Each MESA Series 500 regulator comes with a cylinder pressure gauge and is available in seven preset flow models. The fixed flow calibration gas regulator is not field adjustable.
