Hi, i'm brian with the hvac school podcast and i'm demonstrating the test of smart probes kit and it's got a new case and in the new case it's got space for a lot of different new probes, five 10, i being one of them. It's a differential pressure gauge a manometer and i'm gon na show you how to measure static pressure with the 510. I using some static pressure probes, alright, so the first thing we need to do is zero out the 510. I to make sure that it reads accurately zero the pressure sensor when we position the static pressure probes whenever possible, we want to point the tip towards the direction of airflow, so if the direction of airflow is coming this way, we want to point the tips in That way, i've done a lot of testing and i've seen that it doesn't actually make that much difference in cases where you have fairly low velocity like residential and light commercial.

But it's the correct way so we're gon na do that as much as possible. So i'm actually gon na, take it and place it inside the air filter door with the tip pointing down in this orientation. Well that isn't necessarily a perfect situation. It's gon na be the best way for us to measure our total external static on this unit without having to drill additional holes.

I'm going to place my positive probe in the duct connect the supply duct to the positive connect, the return to the negative. So we have the return connected to the negative and the supply connected to the positive, and you can see that our total external static is point three four inches of water column. On this system. The system is rated at 0.5 inches of water column on the data tank, which means that we're within our specification overall, it's a great test that you can do to a system to make sure that you don't have too much air pressure.

If the test - Oh smart, probes, kit puts it all in one nice easy to use case thanks for watching.
