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

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.

The media could not be loaded. Trabajo con llantas de tractocamion así como de carro y moto, este calibrador funciona perfectamente para todas las presiones, ha resistido varios golpes y salpicaduras de agua, ya tiene más de un mes de uso sin cambiarle la batería, muy buena inversión

I gave it 4 stars to call attention to the fact that it’s low reading does not go to .1 psi. In my case (60 psi model) it read 0 until the flow through the check valve I was testing was high enough to reach 2 psi. After that it read in .1 psi increments. (Remember to remove batteries when not in use as they can leak causing internal damage.)Appears to be a well made good product. It does not show the max psi until it is turned on.

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.

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

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

Good

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.
