I service industrial burners for a living. Customer pay good money to fly me around the world to service their equipment. This series of manometers by Extech are the ones I use most often. They are reliable, remain accurate, have very useful recording and min/max/averaging features. Extech makes this item in 3 ranges (this on is 0 to 0.5 psi). It also comes in 0 to 2 psi and 0 to 5 psi If I had one nit to pick, it would be that they turn on too easily. I must remove the batteries to keep them from accidentally being turned on in my bag or shipping box. They do turn off by themselves after a few minutes, but I have had them drain the battery during transit.

I am very happy with this instrument
Excellent. I used this for flow measurement on a jobsite where I was on ladders, on roofs, and on manlifts. I had a liquid manometer with me as well, but there was no way I could have used it under those conditions.. I compared readings side by side with a conventional manometer, and ti was a perfect match. It even has a magnetic strap to hang it securely on a metal surface to make it even easier to use.

Easy to use and great display
Use this on most service calls to check static pressure. Long battery life. I use a rechargeable so no big battery expense. I put flex tubes on it and some small nylon tubes at end sliced at angle so I can simply jam into duct and get measurement. Nice hard case that I can keep in van without worry of being destroyed.

Great tool!
Works well! Hose a little short for what I need - but otherwise great. But one could expect no less from Extech or FLIR.

Ok
HVAC tech. Not accurate compare to expensive one. But it is still working good and good to buy because of cheap price.
