Where can I get a low pressure gauge?

Hi all,

I would like to do some testing of exhaust back pressure, but I don't know where to find a low pressure gauge to do it with. I would think something that maxed out at about 10 or 15 psi would be about right. Any ideas?

Have you tried Grainger or McMaster-Carr? Both places offer industrial process gauges in various ranges.

No, I haven't. I'll check grainger, since I have one in the city I work in.
