Review on Enhanced PIC 102D 158F Connection Pressure Internals: A Robust Solution for Improved Performance by Vincent Burton

So everything is relative. For the price I paid it worked well, some might give a negative review because they had higher expectations. Here's the thing, it works fine, just don't leave it in a vacuum for a week, mine is after all. suddenly, suddenly Read an even lower vacuum reading because there is more vacuum than free space. Instead of -30, it looks more like -35. I can still use it to see that there is no vacuum leak, just not an accurate gauge. Normally the gauge should operate at a constant pressure/vacuum indicated on the dial, I have not exceeded the reading on the dial. I would have bought it anyway, but I got this in addition to a more expensive one that I don't need. use for test bench. This may be more appropriate for cases where a temporary vacuum is applied and then released again.
