Uharbour Digital Low Pressure Gauge with 1/4'' NPT Bottom Connector and Rubber Protector , Range to 15 psi, Accuracy 1% .F.S.

Seems accurate within 1 psi

Product.

Actually works under 5 psi

This is the 3rd pressure gauge I have Bought through this Company. The seller ships fast and gauges works great. NO problems backlighting make nice to read in the dark or evening.

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.
