Digital Low Pressure Gauge with 1/4'' NPT Bottom Connector and Rubber Protector by Uharbour, Range to 30 psi, Accuracy 1%, Resolution 0.1psi…

Finally, I found exactly what I wanted - very low pressure measurement with fear of destruction at somewhat higher than rated pressures. Great, great product.

Product.

Just to make sure the calibration is right I recalibrated mine to match regulator pressure. I just do my own auto repair work in the garage and about to do a little bit of painting. So it really doesn't have to be spot on for me whatsoever Just close. Especially since I'm going to you using a regulator at the gun for painting. A lot of complaints about the fact you can't cut on the screens backlight after it cuts off without changing mode. I figured out you can, You just hold down the power button for 2 seconds. Once again not a big deal for a garage use pressure gauge in my opinion . Plus if you want top quality stuff you have to spend top quality $$$ money for it sometimes. It's a cheap digital gauge when compared to one that cost five toeight times the price for a commercial grade type digital gauge. Can't say how long it's going to last I only had it hooked up about 3 weeks now.

Yes, I know it's battery powered - so what. Keep some extra AA's in your air bag. You can read it in very low light which is a big help if you come off the trail at dusk and need to air-up before hitting the pavement.

The gauge itself is decent quality but it doesn’t auto shut off unless theres no pressure in the system. If there is steady pressure like a closed system with the compressor off, it just stays on. I had to vent all the pressure to get it to auto shutoff. You can manually turn it off, but mine did not turn off manually at first. After I held down both buttons for 10 seconds it seemed to restart and locked up for a few minutes but when I came back, it was able to turn on and off manually with the on button and worked fine.
