GASCO’s 75 series demand flow regulator is designed for use with instruments equipped with a pump to draw the calibration gas. The regulator provides the exact amount of gas the instrument pump requires. 75 series demand Flow regulators are designed to be used with 34, 58, 74, and 116 liter aluminum cylinders as well as 103 liter steel cylinders.  75 series demand flow regulators are constructed of nickel plated brass and offer a 1200 psi pressure gauge. 

NOTICE:

GASCO's 75 series demand flow regulators are not designed for use with highly reactive calibration gas mixtures such as chlorine, hydrogen chloride, ammonia, etc..  GASCO's 70-SS stainless steel series regulators are better suited for such applications.
