Edit, Sept 2019: Added photo of Pelican case full of these manometers (two layers deep - several ranges). I really, really like these!

Original post: I really like this series of Extech manometers. I own 3 of the 0-0.5 psi, 2 of the 0-2 psi, and one 0-5 psi. I also own about a half dozen Dwyer manometers of various scales. The Extechs are more useful for my work as an industrial burner technician. The min/max/avg feature is very useful for catching transient readings or smoothing out a fluctuating pressure. The display can be illuminated which comes in handy in the usual grimy/dingy/dark plants. On occasion I've used the data logging software, but it's not the most useful feature. The standard 9 volt battery last a very long time. I use rechargeable batteries in mine and get weeks of service between charges. They have an auto power-off feature that can be defeated if you want the manometer to stay on indefinitely. There's even a 120v wall outlet power supply that you can fall back on if the battery is dead. I've only ever had one of these break. The screen was cracked while packed in my luggage. I put these to the test on a daily basis and continue to buy more.

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.
