If you want to know whether or not there's restriction in your HVAC ducts, your…
If you want to know whether or not there’s restriction in your HVAC ducts, your furnace filter isn’t right for the system; is closing vents to a room creating issues that will damage your HVAC or you aren’t sure whether you need to add makeup air supply to your exhaust fan, this is the tool you’ll need to figure that out. The manometer reads differences in air pressure between separate points in your HVAC system or the difference between ambient air pressure and another source of air pressure. Generally speaking, if the difference between two points in your HVAC system is greater than .5 inches of water column, you may have a restriction that could cause premature wear of the components and indicate problems with your HVAC. This manometer comes with a small selection of adapters, very brief instructions in the manual and several different lengths and types of hoses. The included long hose is sufficient for most purposes, and the meter has a clear backlit display that is easy to read. it is easy to zero the meter and it will take a sample over time to allow you to take measurements as you cycle through different system functions. It can switch between several units of measure, and appears to be well made with large buttons that are easy to push even while wearing gloves. It does not appear to be safe to use in explosive or flammable environments, and I would not attempt to use it in the presence of flammable vapors or gases. It doesn’t come with batteries or a carrying case, but given the quality of case that these things seem to come with, you’re better off buying something better made for your purposes. All in all, it appears to be a solid meter for the price.

I love the build quality on this and how crisp the display is.
I love the build quality on this and how crisp the display is. The included accessories also cover most of the bases for hooking up to pretty much anything I could hope to measure with this. I compared readings against a cheaper digital manometer I picked up used somewhere and they seem to be agreeing pretty closely. Response time is good, and the data logging feature is a welcome bonus if I want to try to record some sort of system response down the line.
For the super nerdy among us I found there are some serial communication pads exposed though the battery compartment.
Overall a very capable tool!

Great tool for the workshop!
I really like that it supports multiple measurement units (Kpa, psi, inHg, etc.), which makes it very flexible to use. I’ve tested it on the intake manifold vacuum, brake booster pressure, and even crankcase pressure without any issues. The included adapters fit different pipe sizes perfectly, so it’s ready for a wide range of automotive applications. Definitely a must-have for anyone working on cars.
