I've been trying to find an affordable (<$150) 2-port manometer that measures pascals, down to the tenth of a pascal. Is seems that there are a lot of units that can measure in IWC at low levels, but not in pascals.

I don't need one that does anything fancy. I just want to see pressure. Has anyone had any luck finding such a unit? If so, please let me know!

I found one (after lots of searching)! It appears to cost around $350.

Dwyer makes one that measures kPa to .0001 resolution. If you don't mind moving the decimal over in your head, it's an easy way to save about $450/manometer.

The model # is:   Dwyer  477-000-FM


Actually, you don't even have to move decimals in your head. It also reads in pascals to 0.1 resolution.
