Digital Low Pressure Gauge with 1/4'' NPT Bottom Connector and Rubber Protector by Uharbour, 0.35-30 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.

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.

Good product overall; checks accurate against other gauges, easy enough to read and updates quickly.However, it appears to allow a very slow leak. I have two of these (so sample size of two, not just a single gauge) mounted on quick-connects, allowing me to put them wherever I want in my air systems. When I leave either of them attached to my tank, it loses pressure over time (a few psi/day in a 20-gallon tank); by contrast, when either of my two analog gauges mounted on the same quick-connects are attached to the same port, the tank holds its pressure indefinitely. The analog gauges are also always-instantly-readable, where as these require pushing a button to turn them on, so for tank pressure monitoring these don't replace an analog gauge.If you're not using these in a static-pressure system, then they seem to be a good product.

Es lo que ocupaba

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

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

works perfect and yoy can set your pressure marker to what you want your presdure to be set at

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.

Je suis maître technicien automobile et j’avais besoin de remplacer le cadran d’une jauge à pression de pneus défectueuse.Celle-ci fonctionne très bien. Je l’utilise depuis plus d’une semaine.Bien heureux de mon achat.

Manometro preciso,testato con altri strumenti professionali e coincide,sembra affidabile fino a 0,15bar sotto non ritengo sia il suo lavoro,infatti ho preso anche quello da 0 a 1bar. Se posso permettermi,una raccomandazione per chi lo acquista,non usatelo su sistemi che superano o possono superare il suo campo di misura,altrimenti lo rovinate subito. Per esempio,non usatelo direttamente per gonfiare pneumatici,anche se questi andranno a pressioni entro il suo range di misurazione (0-4bar esempio),il compressore sicuramente fornirà molta più pressione a monte,il che potrebbe stararlo. Solitamente i manometri con buona precisione si usano solo per sgonfiare,proprio per non andare fuori scala,tutto qua.

Ne ho comprato 2... 1 non funziona

Actually works under 5 psi
