Can the argon meter be used on CO2?

Can not, argon is stored in the gas cylinder in the gas state, and CO2 is liquid, when the gas is released from the cylinder, argon form is unchanged, carbon dioxide is liquid - gas vaporization process will absorb the heat on the table, so carbon dioxide pressure gauge with a heating device, and argon pressure gauge is not, if the argon gauge is installed in the CO2 cylinder, the long-term use of the pressure gauge may be Frozen or even cracked.
