One of my scenors (#3) isn't reading the PSI correctly. Has anyone else experience this?

I get a different reading from every gauge I use. . .TD seems consistent between tires, though. Maybe battery?

No this is not normal at all, I use this tool every day mostly on pressure tanks and it must be within a half of a pound (I test this air tool for accuracy once week in the shop) and it has always been right on...Their are a couple of things I can think of...First operator error, you must have this pressed perfectly square against the valve stem, if you hear air leaking you will never get a correct reading, due to the fact that hearing air leaking is constantly lowering the pressure...Second have you tried the gauge on something different, like another tire and did you get the same results...? If this is the case their maybe some thing wrong with the rubber seal inside the gauge itself, take a small strong light and look inside the gauge were it makes contact with what your testing, to be sure that the rubber seal is not damaged...If it is damaged than this is the problem and why you hear the air, you'll need to send it back for a replacement...This is the number one thing "AMAZON" does best and quickly...Hope this is the problem and helps you out...Rich.

I just reviewed the Melnor web site and all available PDF documents for this model and it does not have any PSI specification. I feel it would be best to contact Melnor customer service or support directly for this answer.

I don't know, however google PSI and ask them. That is what I would do. Go to the source. W.R.

Mine doesn't do that. It gradually rises or falls according to what the ppm is. Sounds like you have a defective unit.

the same thing happens to me! It seems to be when I don't have it pressed tight and apply pressure to unit.

I am not familiar with that reading. My unit has worked like a charm. I would suggest that you go to the vendor's website. Maybe someone else has experienced something similar. Good luck!

I haven't had any trouble with mine. When immersed or poked into something, I get a reading within a few seconds, max.

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

It sounds like it needs to be recalibrated. Take the batteries out, then reinsert them. Put it down in the flat hard spot where you want to keep it, moving it around will cause this. If you have a small level, you could check that. Then step on it several times, waiting a few seconds in between. i have done this 4-5 times when I get different readings, but then it settles. If this does not work, check your instructions again, if you follow all the instructions and it does not work, I would contact the company. Good Luck!

I have this in-line gauge, between the pump and the valve. I've noticed the cheap pump fights the tire pressure when trying to read it with the gauge. Not sure I like the pump; I suspect it is the pump/gauge that's the issue - not necessarily the 90 adapter.

The gauge reads 300psi, but it only gives me about 120 psig i think, its maybe more like 110 psig, anymore the regulator starts to leak off the extra pressure. This sucks....

Compared to my previous gauges, this one is almost "too" consistent with its readings. Yesterday, all my tires read 33.0 PSI before filling, after filling all read 34.0. I am still, after 4 months of use, a little suspicious. This is a very sturdy, well constructed tool for the price I paid. I am keeping it for the other useful features it offers, but spot-checking the PSI's with my old gauge.

This happened to me too. Sometimes you have to reset the float, but if that doesn't work you should send it in via warranty.

I'v had mine about a year without any issues like you described. I have found I have to turn it on and let it warm up for about 15 to 20 minutes before it will give accurate readings.

There is a gauge on the inside of section1 that lets you know when you are in the correct psi range. We had to guess the other 2 sections by feel. Would have liked it to be more exact, but it worked great for our week long fishing trip. Good luck!

I replaced one in my wife's 2007 Jeep Grand Cherokee Limited. It took a week of driving for it to finally register. The pressure reads about right but after about 12 miles, the pressure reading disappears and I get a message to get the system repaired for a while. Wife and I joke that the "smoking tire has been lit" when the dash display does "dong" to annunciate the error message. Eventually the pressure reading comes back and reads the pressure. Looks like the sensor update rate may be a bit slow for the GC electronics. Hate to demount the tire, again, to replace w/OEM. So yes, replacing one sensor with the Dorman does almost work as desired. I replaced one in my wife's 2007 Jeep Grand Cherokee Limited. It took a week of driving for it to finally register.
