works great for troubleshooting low pressure gas problems anything below 55" ...

works great for troubleshooting low pressure gas problems anything below 55" water column.However,If you work with 2# systems and higher you will just get an error code when over 60" W.C.igf you work high pressure systems deinatly spend the extra money for a quality manometer
but the quality didn't seem much better than the ones on ebay for $40
Steve•November 12, 2014
I'm sure it was accurate, but the quality didn't seem much better than the ones on ebay for $40. In fact it looked identical to those except for the brand label. While those aren't reasons to ding it, mine came through with the power button not seated properly, so it kept turning off and on. It had to go back.
Five stars now 4 stars
Colorado Contractor•November 8, 2014
Great manometer. Very easy to use. Included hoses and two threaded hose barbs. Worked great. Highly recommended.
Update:
Last week I turned this on and it appeared the battery was low. Screen flashed on like normal but faded off instantly. I installed a brand new battery: same result. Frustrated, I set it down rather firmly on granite counter and suddenly it worked like normal. Haven't had a problem before or since.
So while I have a backup, I was surprised (as well as I treat this device) it sort of had a malfunction here. It tests the same as my backup, so maybe some kind of a connection/humidity thing? Specific to my device only? Anyway, if someone else experiences this, just give it a gentle tap. I downgraded my rating a star because of this.

Good meter for a good price.
Michael Berry•April 29, 2014
The meter has been tested against higher priced meters and was spot on with the readings. Very good meter for a very good price. I am happy that I bought it.
