Will this work for measuring air velocity out of heat and AC vents ?

I think it should work, yet I have never tried it like that. THe meter will see ~1 to 2mph air flow.

I'm not sure what is the lowest velocity it measures--it does clock the approx 4mph when I walk.

This is what I bought this unit for. You can use it for "relative" measurements; comparing airflow from one vent to another or comparing airflow before and after a change, filter replacement, etc.

I am not a HVAC guy but I would think that it could be a valuable tool to measure duct air velocities on a relative basis. It is a sensitive instrument but only measures air speed. I suppose you would have to do the calculations in order to calculate cfm. One of the things I use it for is to measure air intake speeds into duct work I set up temporarily at jobs to create negative pressure within houses as a means to minimize dust dispersal. I love this meter. I always have it handy in my toolbox.

No, it reads the surface temperature of whatever object you point it at. You can't "point it" at clear air -- it will read the temperature of the surface across the room.

Yes, it will. I am very happy with this unit. Since it was comparatively less expensive than some other models I had my doubts. I use it in my country cottage to determine wall, wood burning furnace, and pipe temperatures. Unfortunately, my pipes froze before I ordered this. I like this unit so much, that I am going to order one for my home.

I don't know but expect it will work. I've measured from 20-212 F and seems to be reasonably accurate. I have an Everstar small portable room air conditioner. Reads 52 coming out and the tube for exhaust reads 105. Currently it is hot and humid outside. Price is right.

should work, has adjustible pressure and temp settings. The only thing you would have to do is tap into the wire harnes for power to the monitoring unit needed to see information.

I'm pretty sure that this isn't designed for spotting the air itself, it is designed for testing the temperature of the surface area itself. So you would be able to spot where the wall is colder, but not where the actual leak is coming from. I think you are right, you need a thermal camera.

I've never tried but I would assume not. I believe it's only meant to measure air temperature.

If you point the gun precisely near/at those spots, all you will see is if the surface temperature is different and that could give you a clue. But again this temperature gun will only measure surfaces and not air. Your best solution should be, as you said, a thermal camera.

The manometer will work if sealed properly. I have a variable speed radon fan and run it at the lowest speed that maintains air flow in the vent pipe. When the fan is on the highest speed there is a humming sound.

Yes, it can, and that is how I ended up with a broken unit. It is supposed to work, but when I applied vacuum, the gauge topped out and has not moved since. (high side). I was able to pull a vacuum and do the work. I think I got a bad unit. Still, all together, it cost less to buy this and have it go bad than to have the A/C work done in the first place.

Yes, it will work great for a heat, light, vent system. Make sure you have a dedicated 20 amp, 12/2 copper, home run, wire.

I am currently using it to test my coils and it does work to a reasonable level. It will definitely will tell u if your coil is safe and the rough resistance, but I would not consider it precise enough for the serious vapor.

Should work . Husband even used it to check for heat / coldness of our house windows for drafts . Bit, the main use in our house is temp of oil for chicken wing and deep fryer for Turkey . When he gets it he's checking temps all over even my boobs... Donna lol lol

The specifications for the Ventamatic XXFirestat should tell you. It is designed for AC Current.

I set mine up to draw fumes or hot air out of my garage. It fit perfectly into the opening of a roof vent. It is only max 400cfm so your volumetric flow is not high, but to move some fumes it works. I found paint spray vapor deposited on my fan blades so it does work somewhat ok. But it is not sealed, spark proof or waterproof so think about your application carefully & be sure you are not creating a hazard

It can be used for such a purpose but with out an air flow meter is hard to figure out what any change would do to any system. You could always over power a system then use an adjustable inline damper to bring the air flow down to what is needed.

No. It is meant to be used as a measurement device for negative air pressure.
