Is this gauge calibrated to read 14.7 psi at sea level or 0 psi at sea level? Thanks

I'm at 11 to 14 feet above sea level and it reads 0 until you hook it up and turn on the water. My municipality delivers our water rated to 60#psi related by the meter and two different households had readings of 60 and 62. If you live in the mountains and have a water supply rated to let's say 80#s then it would read out 80#s on this gauge as all things are relative.

It doesn't have a port for a gauge. You may find an inline gauge but you may start reducing pressures.

I have three very good air gauges. When I compared them, they all read very similar. This gauge reads down to the tenth of a PSI so I would say it is the most accurate gauge that I own compared to my other analogue gauges.

After 20psi there are five intervals for each increment of 20psi, so they represent 4psi each. From 0psi to 20psi there are three intervals over a narrower physical distance. That's where the gauge is pretty non-linear--I wouldn't read too much into readings below 20psi.

Gauge is inaccurate during inflation. Compressor must be turned off to get true reading.

I don't have a gauge to know how low but I am pretty sure you can get it below 5 psi. Works close to a need valve.

No...if its full of air... tank gauge should read bout 135 which is the factory cut off setting and your line guage should be set to at least 90 psi to run air tools

The pressure gauge used to both read the pressure, and set the maximum pressure, has a max setting of 150psi. The trip needle would probably make it cut out at 148ish. So in theory it should be capable of this pressure. FYI the compressor is fairly slow. I used it on a tire with 20 psi, it took about 3 minutes to fill it to 35 psi.

The ohm rage for the gauge is 33 to 240 ohms so it should read in the correct range it is a negative ground unit

I don't have it in front of me, but I believe it has 5 psi increments from zero to 150.

The gauge reads up to 160 psi but the label on the side states that the maximum working pressure is 120 psi. I have used it on bike tires for 100 psi but use it mostly on car tires. It can overheat and shutdown if doing tires one after another but if I let it run not connected to a tire for a couple of minutes, it seems to cool it down enough to keep from overheating.

Yes, the one I received was 14 gauge. I've been happy with the purchase and use it for my electric lawn mower with no problems.

If the gauge is in line after the tanks are coupled, it will measure the relative pressure, as noted by a comment from Mike. I would ask a "pro", though, before I would try to cobble something together.

No...this is a simple inexpensive gauge, not a precision instrument. I didn't get a chance to compare it to a reference gauge as mine quit working. Nice gauge for the price though (if it works) because of the lighted tip.

Mine accurately measures whatever pressure is in the tire up to 60 psi. Either you have a faulty gauge or you have only 15 psi in your tire.

Mine is only PSI and gauge is heavy brass. I believe you can go directly to the Company to order the scale marks you need.

I would get a 0-30 psi gauge. It would be more accurate for a low pressure reading.
