Only thing is I wished it had more fittings to fit different applications like my Ronna tankless water heater. But did come with one just wasn’t the size I needed. But that was fine. . Simple to use and instructions really could use some work. But for the price it worked well. I compared to a manometer analogy. And it was accurate

I bought a number of these manometers to distribute to my plumbers and they have worked great.The price is a very good value as well

Very good value for the price. Measured comparatively well against a more expensive unit. I would have given it a 5 stars if the display was more intuitive and the instruction better written.

Save my butt diagnosing a car, helped me figure out what engine parts to replace. Actually worked so well everyone in the shop now uses it! Just wish it had a couple of different sized nipples for the hoses

I bought this to diagnose an air pressure switch problem in a heating system. A pressure switch that's supposed to close when experiencing a 1.5" WC (Water Column) amount of negative pressure wasn't closing, so I bought this to determine if the switch was bad, or if I have a problem/leak in the combustion chamber (heat exchanger).If you're unaware, pressure as measured in "inches WC" is WAY more sensitive than PSI. I think the conversion is something like 1 PSI is equal to like 27.7 inches water column. And I needed something to detect 1.5 inches water column, which is 0.054 PSI. Many of the analog gauges just aren't good at picking up really low pressures like that. But, one of the modes of this meter is to measure in inches WC, so I decided to try it.The one thing I noticed is, just sitting there, not connected to anything the gauge reads negative 0.27 inches WC, so it's claiming there's a slight vacuum in regular air, which seems unlikely. So, when I connected it to the heating system, it read 1.57 inches WC, so I wasn't sure if that was really 1.57, or if I needed to manually subtract out the 0.27 reading.I wish there was a way to zero the meter out, meaning, I'm at regular atmospheric pressure for my temperature, let's call that zero, so that when I measure the appliance (heater), I can see the delta from normal, but with the extremely short users manual that comes with this, I don't see a way to do it.In the end, the meter showed I had negative pressure in the combustion chamber, which is what's supposed to happen (to prevent carbon monoxide build up), so I guess it worked, I just don't know how accurate it was. But good enough for the weekend HVAC repairer like me.
