## Questions & Answers

**Q: Wouldn't the 2psi version do everything this one does and more? They both have 0.001psi resolution.**
A: If all you care about is 0.001 psi resolution, then you should be fine with the 2psi version. However, the 0.5psi version does have better resolution, as can clearly be seen in the spec sheet, ie, 0.01mmHg vs 0.1mmHg. So it just depends on your application, but it would be a pretty rare application that requires better resolution that 0.001psi.

**Q: Is it intrinicly safe for testing natural gas pressure?**
A: No moving parts, and a sealed assembly would lead me to say yes.

**Q: This includes nist-traceable calibration certificate?**
A: This does not come with the NIST traceable certificate. The Extech part number HD750-NIST will include the cert.

**Q: How many decimal places does this unit display to the right of the decimal when using "in wc"?**
A: Two. It reads in hundredths of inches water column. It's probably not that accurate, but it displays them.

    Professional service technician's first choice.
  

*by R***S on Reviewed in the United States on 2 September 2017*

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.

    It works
  

*by D***N on Reviewed in the United States on 17 September 2013*

The manometer works as advertised. I've used it for static pressure tests on HVAC equipment and leak testing on natural gas/ lp lines. The casing is molded plastic and could stand to be a little more rugged. The battery cover in particular seems to need refinement as mine has a tendency to come loose. I have not tested the software or usb connection. I have no use for that feature, however, the recording feature is great for pressure testing lines. Update. Having owned this meter for about 2 years, I can tell you that it is over all a good meter, but has a few serious issues.  The first problem is the temperature range.  If you leave it out in your vehicle in below freezing weather, the display screen goes out. The second issue I have had is that the case has cracked in the upper right corner by the screen.  Now the screen will only come on if I squeeze it together tightly.  Right now, I'm looking into getting a new manometer and I don't think I will be buying this one again. It just isn't rugged enough for my use.

Bought this to measure small amounts of gas pressure. Works great and very accurate
