For the device airtightness test, which is better – nitrogen/steam/air – depending on the available conditions?
Under permissible conditions, nitrogen is still the better choice; water molecules in steam and oxygen in the air can have a significant impact on the surfaces of certain equipment.
It’s best to clearly state what your device is like and what gases it is suitable for testing. That type of gas is inexpensive and easy to use, making it suitable for such purposes. One shouldn’t use a sledgehammer to crack a nut; cost considerations are quite important.
Dry air or nitrogen can be used. But it must be dry.
