Regardless of what they call it, it doesn't work well.

Much faster to just air up, eyeball it, and check it a few times.[/b]
Here's a quote from the link for the inflator/gauge:
"Please note that the gauge will not show actual tire pressure while inflating. Actual pressure is shown while the gauge is clipped to the valve stem and the tire is not being inflated."
I bought a similar POS (Viair) & never used it once I realized it didn't work how I though it would.
I finally ended up purchasing one of those heavy duty gauge/inflators you typically see at service stations, the kind with the reddish rubber hose & pop-up brass pressure gauge (Sears); just conect to source hose with quick connect & squeeze the trigger to inflate, and when the trigger is released, the brass rod shoots up & gives approximate pressure. I realize it's not incredibly accurate/precise, but I feel it's good enough in most cases & will certainly take abuse.
