Digital Low Pressure Gauge with 1/4'' NPT Bottom Connector and Rubber Protector by Uharbour, 0.35-15 psi, Accuracy 1% .F.S.

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

Great deal. I used for my gas inspection where the inspector wanted a gauge that showed percentages of lbs. He signed us off on our gas test.

Using this gauge in a diy tire inflator.Works great !LCD display turns off after about a minute.The backlight is helpful and turns off after around 10 seconds to preserve the batteries.When you apply pressure to the gauge again before the LCD times out the backlighting turns back on.Accuracy is spot on.****Updated ****Starting to give inaccurate readings under 25psi.Ordered a replacement.This gauge lives in my jeep and is used all week at work also.It was used for fuel pressure once.(not recommended,but it worked in a pinch)I'm happy with the lifespan under the abuse.

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.

This 0-15 is very inaccurate at the lower range. I tested it against a accurate inches of water (27.7 to 1 psi) It reads 0 at 3 psi. It reads at 3psi when it actually 5.5 psi. It reads 5psi at when it's 7psi...I wasn't able to test higher than that but it seemed to get better in the higher half of range. Other then that it is great.Update edit: from 1 star to 5. So yesterday something happened. I push the function button and switched through the different meassurement types and presto. When it got back to PSI... THE ACCURACY WAS THERE! It is now spot on, not sure what happened, but now it's accurate down to about 1/10th of 1 psi. So from now on to confirm it's working correctly I'll test it by blowing into it. I can blown 1 PSI by mouth and that's what it should read. Before I inflate my windwing.

The media could not be loaded. Seems to not be registering or the display is broken on the battery indicator for the air gauge. It also does not come with the Teflon tape it does, however come with batteries.Update!!!The company reached out to me and made this right, actually stand behind their product to go out of their way to fix things I would buy again

Seems to be a lot better quality than the ones that come with or on the tire fill that you buy. One of my favorite features already is that you always don’t have to be turning the light on it automatically turns on when you put pressure to the device so as soon as you put your air truck on the tire the light comes on and there’s a separate button for that light and a separate button to change it for psi or whatever form of measurement you want to use so every time you push the button it doesn’t change your setting I found it to be really accurate within a half or better. Very happy so far with the purchase

I really wanted these gauges to work - I purchased qty 11 of the -15 to +15PSI model. I tested these in a jig with a 0.25% FS calibrated gauge at various pressures.Good: Gauges were linear and accurate to better than 1% FS. Some gauges drifted more than others but within 1% FS.Bad: This was deal-breaker for me & I had to return them. Occasionally (~1 in 10 power turned on; LCD off -> LCD showing value) the gauge would ZERO (i.e., read 0.00) even though tank pressure was different. ALL gauges in test jig had same problem so it's likely to be an inherent flaw to the design (firmware bug). Buttons could not correct this issue, however I found that removing batteries and inserting them (with gauge still under pressure) would return gauge to read correctly!Reading reviews finds examples of others running into same issue: turn on gauge to find it reading 0.00 PSI. If you were to vary pressure in the tank (I was using regulator), it WOULD register higher values correctly and lower pressures as negative.Last 2 photos show the flaw in action. With system at some pressure (it didn't make any difference if 0.5 or 15), gauge would power on to 0.00 with nearby gauges showing correct pressure. I don't show this, but removing battery and putting back would restore gauge to proper operation & show system pressure (again).Photos show jig I used (manifold is mcmaster-carr part #6527N104) and pressures across 15PSI down to 0PSI.
