I actually own two +/- 2psi manometers myself and hence the reason for the question. They have 0.01" H2O resolution.
The funny thing is I went looking for a +/- 1 psi hoping for better accuracy but with the +/- 1 psi having a 1.0 % fsd accuracy and the +/- 2 psi having a 0.3 % fsd accuracy, then the latter would appear to have higher accuracy.
I paid a very similar price to yourself for mine.
