You can change the gauge to one that has a finer resolution of lower pressures. Keep in mind though, that regulators also have a range of delivery pressures in which they can work; if the minimum is (say) 40 PSI, then getting a gauge that can resolve finely in a range of 0 - 40 PSI would be pointless anyway.
