I used this to adjust the speed (combustion chamber vacuum) of my combustion blower on my pellet furnace. Instructions were easy to follow, and it worked fine and had the accuracy I needed.

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.

The product came with its brand name missing letters. I install a brand new 9V battery and can barely see the screen unless from an angle. Hook it up to a gas line and the reading is off the charts. I used a manual one and got the correct readings. Poorly disappointed. I only purchased this because Amazon had it as Amazon's Choice. I trusted them thinking they only recommend quality stuff. I'll be returning this tomorrow.

Used it once. Appeared to take readings properly. However just after the return period expired I dropped it from hip height (in the case) and it broke. Pretty flimsy construction which is not really suitable to a tradesperson. If you’re looking for a cheap option for occasional measurements this might do, but definitely get the extra warranty.

Recommend this tool, I compared it to a more expensive one and they read the same pressures,only downfall is that you have to figure out and mark the pressure taps + and - as they are not labeled. I would purchase it again. Just as good as the supco one that looks identical to it,but half the price.
