10.2 ACCESSORIES
10.2.1 Zero Gas Regulator, M1132ZX
This regulator controls the gas pressure of the zero gas cylinders before it reaches the calibration unit. The dual stage regula-
tor is highly recommended for services which require a near constant delivery pressure as the calibration source decays (See
M1133AR). Air diffusion and absorption, desorption and off gassing are minimized because of its stainless steel construction.
NOTE
This regulator is used on a “zero gas” cylinder with a CGA 580 connection. The Cylinder connection must be CGA580 (used for <5%
oxygen balanced in nitrogen).
