Used this tool for the first time with no knowledge of it. I installed my own furnace and it worked great. I recommend it if you're wanting to DIY your own HVAC.

It’s off by 0.4 psi when i test my static pressure. Just buy a better tool

Does what it says. Arrived quickly. The one downside is that the tubes are 1/8 and many gas valves have a boss tap which requires a larger tube. Should come with an adaptor

Only used it a few times and I'm getting pretty wild results. It seems to be super sensitive... The kit I'm testing might be way out of spec or maybe I'm doing it wrong, but more likely, this thing is somewhat cheap and cheerful. Also the tube supplied is too small to fit on to anything useful.

Me gusta mucho lo intuitivo que es. Lo que menos las mangueras que trae .. veremos lo que dura

Got this to test for pressure to make sure appliances are getting proper pressure. So far in testing seems to work pretty well.

Last year I had a need for one of these a couple of times. Not having one I did a sort of makeshift job of adjusting the device that I was working with. Got them close and they have worked just fine. So when this was offered I placed the order.When it arrived I was a little off balance as I do not have a lot of experience with these meters. After a little studying I was able to understand how it is used. I was surprised to find that my old adjustments were very close to being correct.Includes the meter, a couple plastic tubes, an adapter for installation when making measurements, a nice case, a 9 volt battery and an instruction sheet.The quality of this device is top notch for the price. I can't speak for how accurate it is because I have limited experience as well as no test equipment to determine its accuracy. I can say that it showed my original adjustment was close and that should be a good indicator that it is somewhat accurate.I have used it twice so far and, I am pleased with the ease in which this tool is to use.
