Glad I got mine when I did because it looks like the price went up.  I paid 99/134 and now they are 119/149.

They just raised it 3 days ago. It was on sale for 134.

Got them in yesterday, and did some testing. The P9S came uncalibrated, so I zeroed it. I also tested multiple times through the full scale. I came to realize that the gauge needed to break in a bit, because after  going through the full range, I needed to rezero the gauge. The glycerin filled one definitely feels nice, has a good heft, and the stainless case is nice, and it is also a bit larger in diameter which also makes it more pleasing.

 

With all that said, I am thinking of gradually getting all of the P9S gauges so that I can rezero them. 

 

I am also thinking of getting a higher accuracy gauge like this one: https://www.amazon.c...d=IHWS9MBE1CTK5

 

Then build a simple calibration setup to calibrate all of the P9S regularly, especially once they break in. The only thing is, that .5% accurate gauge is so expensive! I may just go for the 1% that is cheaper: https://www.amazon.c...=I183A11ROC0S0I

 

The reason why I would want the calibration setup with the P9S, is because I would want a way to check and rezero the gauges since it has a pretty wide adjustment, and I would be afraid of it being knocked or drifting over time.

I am glad I ordered mine Thursday, even got a free SS growler too.

Free growler till the end of Feb.

Why do you want to spend so much cash on gauges? Did I miss something?

Haha. I know that a number of my gauges are off, and until now I didn't have a way to check. When I was testing last night, the gauge on my regulator was consistently 1 psi higher than the two new gauges. The two new gauges, after zero, were within .2 psi of each other or so (guessing between the tick marks).

 

Pretty much all my gauges are from used equipment that I bought many years ago, or the cheapest gauges I could find at the time. I felt it was time to get some more accurate gauges. I want to be able to trust the pressures that the gauges are showing.

 

I like that the P9S allows me to rezero it, but if I really want to have accurate gauges, I need to not only be able to rezero the gauge, but I also need to have a reference gauge that I can trust more than any other that is not rezero-able. The only thing with that though, is those gauges are really expensive - NIST traceable were all at least $100. Cheap digital gauges were only accurate to within 1%, similar to the decent mechanical gauges, and the nice digital gauges seemed to float between $200 and $300.

 

I am using a Tee to do my checks between gauges, and I can also use the setup to check the gauges on my regulators.
