U Ei Em201 B Test Dual Input Differential Manometer Model: Em201 B

I purchased this so that I could verify and adjust the gas pressure on my furnace. The air coming out of the vents was cold when the heater came on and I knew this could be the issue.I replaced my filter just to be safe and then crawled up into the attic, made my connections and discovered the pressure (set previously almost a year ago) had been set way too low.Checked the manufacturer info and made the adjustment...........done.The Manometer is made very well and worked perfectly for me. Just a word of caution; if you are unsure about how to go about doing this always call a professional, this should not be done by just anyone.I do have experience in the A/C and Heating industry which is why I did it myself.

as expected. works fine. purchased for my grandson who is in college taking heating and air conditioning.

Delivered fast, and product had been working good for about a year

Setting up a new 125k BTU heater in the shop. This helped me set the manifold WC. Very easy to use.

Works great
