MEASUREMAN 2-1/2" Dial Size Digital Air Pressure Gauge with 1/4'' NPT Bottom Connector and Protective Boot, 0-15psi, Accuracy 1%, Battery Powered

Used it about 5/6 times before it started leaking from the casing... Not recommended.

This is a nice upgrade to a tire inflator that came with a less then useful or reliable analog needle gauge. Rubberized boot over meter protects against shocks, and it uses two AAA cells which are common and cheap to obtain. Update: Had it for about a year and discovered it has a white LED on the rear which can be useful to illuminate a valve stem in the dark, it can be turned on by hitting the power button. Still holding up well with no errors or issues. Big improvement over the cheap junk analog gauge that it replaced.

Unboxing review: Ordered 6 nos, 1 was without battery, 4 was with the battery seal. Further after usage we would know the quality and durability. We will update the review after 3-4 months.

Inexpensive, accurate and consistent. I bought this to replace a damaged head on an inflator. It works great and is within .2 lbs of a much more expensive gauge.

I work on trains. Part of our inspection procedure & repairs requires us to check air brake and air spring pressures ranging from as low as 6psi up to 160psi. We have a shop regulated master air gauge that is calibrated yearly for accuracy and I checked this gauge right out of the box and it was spot on accurate. I've been using it for a week now and it's awesome being able to quickly read my pressures. The ONLY downside I see is that it seems you cannot calibrate it. I will check it weekly to ensure it maintains it cal. Another minor gripe is that backlight turns off after X. amount of time, and pressing a button doesnt turn it back on. However, a cool feature I noticed for someone using this as a tire gauge, it has a tiny LED light on the rear of the gauge to illuminate your tires valve stem at night.

Used it to replace one on a different manufacturer's tire inflator. It was easy to install and worked right out of the box. No setup and seems to be accurate. Found out during first couple times I used it that it has a rear pointing work light for night time emergencies.
