Calibration gas regulators do exactly as their name implies. They screw into the fitting on your calibration gas cylinder and regulate the flow to the value the manufacturer has recommended. They simply turn on and off with a thumb screw and allow the flow rate of the regulator to come out.
These items usually last for many years and are simply refitted to your new cylinder when you have exhausted or can no longer use the gas in the cylinder it is on.
On demand regulators are fitted in exactly the same way but are used in conjunction with the manufacturer’s calibration / bump test station as they require a vacuum to cause the flow.
