Manometer, Professional Air Pressure Meter, Dual-Port HVAC Digital Manometer Gas Pressure Tester,12 Selectable Units Differential Pressure Gauge, (Included Battery)

This worked very well to adjust gas pressure and measure ststic pressure on two new furnaces. I had to purchase 90 degree angled probes and some tubing to use it for static pressure and it worked well once I realized not to measure return and supply at the same time which doubled my static pressure reading.

Great product for a very reasonable price!!

Great meter for price

I had a propane generator installed and I needed to check the pressure on the regulator. I used this equipment and it worked perfectly for my needs. It was easy to read and understand. I love the caring case so I can keep everything together.

This item works great. I used this a few times to adjust my motorcycle throttle synchronization and to check to furnace air pressure with for the inducer fan.

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.

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

The media could not be loaded. I recently purchased this Manometer, Professional Air Pressure Meter, Dual-Port Manometer Gas Pressure Tester, 12 Selectable Units Differential Pressure Gauge, HVAC Digital and I could not be happier with my purchase. It is a great tool for any professional or amateur in the air pressure measuring industry.This manometer is designed to accurately measure differential pressure of air or other non-corrosive gases. It has an easy-to-read LCD display and 12 selectable units for precise measurements. The device is also equipped with two highly sensitive sensors that can measure up to five inches of water column. This makes it ideal for use in HVAC systems and other applications where precision measurements are necessary.This meter is made from durable materials, which makes it ideal for long-term use. Additionally, it has a strong, sturdy construction that ensures accuracy and reliability over time. I’ve used it on several occasions and have found that it performs consistently and accurately every time.NOTE: It is extremely user-friendly and provides precise readings every time.
