Pressure Testing the Filter system, What meter to get?

I'd like to test the pressure drop through my filter system to see if it is overkill. What kind of meter can I buy to do this? Basically a barometer with a small tube that you can put thorough the sheet metal sounds like what I need. Do they make meters like this?

You can construct your own Manometer by using a clear plastic tube, stapled against a small piece of plywood, slightly filled with water... kinda the same thing as a water level. It's crude but you can measure the differential pressure by "Inches of water".

If you insist on buying one (a U-tube manometer) then Dwyer instruments can be purchased through Grainger & others. There's also Magnehelic gauges and so forth, but that's probably way overkill for your application.
