Hey guys im attempting to set up my SPD and already had to return a pressure gauge manifold simply because it didn’t read microns. Sure i prob could’ve converted the units given but with this process being terrifying enough i decided not to add additional hurdles. Any suggestions on inexpensive gauges? How about the one in my link?..

I’m a cheap ass and went with this till i can afford a better unit it has a 1/4 npt fitting

iI looked at that but when it comes to reading microns it looked way too cheap
Agilent 531 sensor reader would be my absolute minimum. Bullseye or yellow jacket 69075

I was just going to get the datasheet whitepapers for a good sensor and write code for a microcontroller and small display with vacuum solenoid N2 purge inlet
5 min Arduino project or rasp Pie

The code is already posted on here for Arduino and pirani sensors which are far more accurate than these TC type sensors. They are piezo based
Thats what I meant lol but I’d Rather just write my own copying and pasting doesn’t work for me usually just easier to rewrite in my own fashion and suit my needs
Thank you @square_root_pharms and @ToOmUcH!! Ill go with the device u listed. I noticed there’s no vacuum hose valves. Excuse my numb noobness but where would i plug that into? Directly to my pump?
Sorry I didn’t mean the program was written merely the interface for reading the pirani sensor I tagged you in that thread
Hey bud couple examples they use a KF-25 Vacuum to 1/4 NPT male

@ToOmUcH thank u very much for your time! I can’t help buy wonder, after adding up all 3 items, won’t i be near the price of a Bullseye gauge??
it depends what your doing
how did you want to construct your forline for your vacuum system
My whole point was I got away with less but I’m def going for the Upgrade with higher precision and writing an application and logging of process time temp vac curves and hopefully be able to export it to excel for Documenting all my runs in the near future
Buy a used 69075 should be less than 150
I decided to go with a decent gauge @square_root_pharms that is used. Im pretty sure I’ll need one of those adapters u mentioned @ToOmUcH
