Got this to fix my furnace. Tested the pressures and it was a bad pressure switch assembly. So, 30 bucks for this tool, and 20 bucks for a pressure switch, saved me a $300 dollar furnace service call. Admittedly I don't have much use for this tool day to day, but I've packed it away carefully and I'm sure if I need it again it'll be there and work well.

Good tool to have. I use it to verify regulator pressure on propane / natural gas generators. Looks pretty cheesy but works well. A must have for the generator technician.

Works great Just had to adapt tubing to my application for testing No problem Great value for the purpose at a fraction of the cost of my other test equipment!

Bought this to test my motorhome’s propane system. Built a jig to tap into the regulated low pressure side of system. This digital manometer was dead on pressure readings. Didn’t believe it could be that good so built a water column gauge out of tubing, water & a ruler...... found the home made and digital to be one in the same.

Half the price but still got the job done. Highly recommended!! This manometer is recommended by a mechanic I know. Half the price of other brands but yet works as good. Seller has got different shapes and types of probe to fit with this device. They are sold separately and you can choose according to the measuring environment. There are many scales and units to choose from, although I am using only some of them. When using both two tubes, it displays the pressure difference. This help me check my furnace, air-conditioner and gas appliances without spending $$ on service calls! It used to be sold stand alone with soft plastic tubings. Packages with stainless steel probes offered recently and making it an even better deal. Minimal packaging which is great for the earth. Fast shipping. Recommended for sure!

Hot this to test my home a/c. Word as expected. It does appear the tempateur in the attic causes the unit to be off. Just zero it out and it works fine.

It's a China unit, it comes under several different names. I use only on my unit, which I was having some issues with the burners not lighting up all at once. I checked the meter in pressure, the reading were good. Then I checked the manifold pressure, it worked as I expected, adjusted to 3.8, and all is better now. The digital display worked great. I'm a mechanic, and I pretty much do everything my self. Lots of good video on your tube, on how to check/repair your gas furnace.

Just what I needed to test the gas valve on my furnace, saved me a ton of money because I didn't need to call a tech to check it for me after all and now I own my own test meter, cant attest to its accuracy have to assume its ok, no complaints from me.

I was using a home made slack tube manometer to troubleshoot my furnace. I decided I needed something better and this had a very reasonable price. Works great, very accurate and repeatable. The package and the manual both state that the battery is included, however the amazon page says it is not. The Amazon page is correct. So plan on providing your own 9 volt battery to power this. Comes with tubing, 1/8" adapter and carrying case. Great accessories.

This has worked very well for me and the price can't be beat. I got a pair of static pressure sensors and use it to measure my furnace, including when the filter needs replacing. Also ordered a used Pitot tube on E-Bay and can now measure flow rate. Note this unit is differential (can be used single ended). Some of the expensive ones are actually two separate sensors so one can get two single ended readings at once as well as the difference between them. But not having that is a minor inconvenience. Range is appropriate for HVAC use.
