You can find the pressure through destructive trial-and-error if money is no object - which it isn't for governments when the target hardware is juicy.

Why would you make each device have the same pressure inside it? That's a bit like hardcoding the same password in each one. Any attacker is only going to have one shot on the actual device they care about no matter how much money they spend.
Really sounds very very easy for any lab that can measure molecular levels of gas.
Even a very sensitive pressure checker in a temp controlled sealed box would do it.
