Release the vacuum. on Gauges & Vacuum Gauges

This thing made me question my sanity. Couldn't figure out why I couldn't hold a vacuum. Finally, after an overnight test with nothing plugged in, I found that the system was good, but something else must be bad. Since there is only one valve connected that separates the flow meter from the pump, the meter loses vacuum. I also found out that Revain isn't listed as an authorized dealer so the warranty has expired and the return period has expired so I'm out of luck.

Pros
  • Gauges & Vacuum Gauges
Cons
  • boring packaging

Good micrometer, suitable for testing, measuring and checking

It comes with a micrometer sleeve but so far so good, I haven't compared it with other micrometers yet, but it seems accurate because with my old micrometer and with this new one they both showed that the vacuum pump shrinks to 20 microns or less, buy a protection plan so they replace it if it fails within 4 years. Two thumbs up.

Pros
  • vacuum gauges
Cons
  • are not reliable

Inaccurate: Vacuum Gauges

This is the second Testo Micron gauge I have purchased and both showed the same results. It doesn't really pull. As you can see, the CPS indicator comes after testo and has a lower value. The CPS is my main vacuum gauge but I love everything Testo makes except for this micron gauge. Identifier behind the micron sensor - accurate and detailed readings, I haven't seen any accuracy with it yet. Also really unfortunate. It's a $200 paperweight for now since the return window is closed. Save yourโ€ฆ

Pros
  • Pressure and Vacuum
Cons
  • Expensive
