AUTOOL Digital Manometer, HVAC Gas Pressure Tester, Dual-Port, Handheld, Temperature & Pressure Measurement, ABS Material, LCD Backlight, High Resolution, Storage Function, 3-Year Warranty

Easy to use and read. Great instruction for use. From perspective of a DIYer so take that into consideration. My property consists of multiple buildings with many different gas (propane) appliances. This tool is great for installing and detecting. I use this tool to randomly check pressure at different locations looking for low pressures possible leaks. Simplicity of the tool makes installations quick and the peace of mind from random checks is a bonus.

Lasts longer than my Klein ET180 manometer (Klein died within 5 months of usage with batteries replaced.) I'd give it 5 stars if the hoses were longer, better to be about ~25", and magnetic back so I could attach it to furnace panels. Other than that, highly recommend over Klein ET180.

This manometer is very well made, feels great in the hand (not slippery) and the buttons are very responsive and well positioned. The backlight makes it easy to read and stays lit for several seconds after turning it on. I was able to read gas pressure on my furnace quickly and easily. I am very happy with this instrument and it works well! The only thing I would change is the hoses are that come with it are very short, like a foot long. It could use a 3 or 4 foot long hose so you could set it on the floor or stand up with it to read it. Other than that, all good!

I checked a natural gas furnace with it and it seemed to work just fine. 4 stars just because.

Recommend. Accurate. Easy to use, pressure is good. Functions well. Size is great. Value is good.
