Calibration Gases
Calibration Gas Connections
The customer must connect the calibration gas cylinders to the MAX300-RTG
without contamination. Details of the connection may vary depending on the valve
option installed. Figure 18 below depicts the recommended hardware for
connecting calibration gas cylinders to the MAX300-RTG.
A common configuration is Valco rotary valves using 1/16” fittings. Each cylinder
of calibration gas requires:
High quality, low outlet pressure, two stage regulator with a stainless steel
diaphragm and appropriate CGA fitting. Please contact your gas supplier
for special considerations such as corrosive gases.
1/16" O.D. x 0.030" I.D. stainless steel tubing. Length as required to route
plumbing from MAX300-RTG to the gas storage area.
1/16" Valco nuts, ferrules, and plugs (supplied with the valve kit).
