Micron Gauge Versus Vacuum Gauge, Part 1

This will be a two part video series. In this video I'll be discussing pressure, vacuum, the different units of pressure, absolute and gauge pressure. Also I'll show how to convert between the different units of pressure. In the second video, I'll do a test to compare a micron gauge against an analog vacuum gauge and we'll compare the results. Enjoy the video and thanks to all for watching!

Thank you Sir for taking the time to produce this material. It can be a challenge to find a channel willing to delve a little deeper. I don’t have the mathematics chops to follow university programs. Greatly appreciated 👍

This video became fantastic after the introduction is finished. Extremely well done and very understandable.

I viewed the entire playlist; Mini-Split Heat Pump Install, Pressure Test and Vacuum. I wanted to thank you for the very professional, educational, and enjoyable series of videos. The subject matter, camera work, and detailed information included in the videos is first rate. I can tell that you are passionate about the projects that you tackle and way you present the information makes it easy to follow and understand. I’m currently installing a mini-split in my garage. Your videos convinced me of the importance of pressure testing with nitrogen and using a micron gauge instead of relying on the compound gauge to determine when a sufficient vacuum level had been reached. I spent more money on tools than I had planned, but It’s like they say: “The cheap comes out expensive”. Better to do it right the first time than to have to do it over. Thank again and keep up the good work!!

I have been watching a lot of youtube videos on installing mini splits and it all seems very diy friendly except when I got to the vacuum testing part. I am feeling a lot more confident after watching your videos and will likely rewatch them to vacuum up all that info. Thanks for taking the time to explain things for a pea brain like me. All the best to you my friend.

We boomers lived through the era of arcane units, no better illustrated than in measurement of pressure. I always wondered what people were referring to when they talked about microns in reference to pressure. Thanks for the careful review!

Wow Terry, you took me back to the beginning of my aviation training when we learned how altimeters worked. Everything is based on on the "Standard" of 29.92, 14.7, on a 15 degree celsius day. Very nicely done.

Terry, I saw your 1and 2 videos on gauges vs micron. I strongly believe it's a very impressive and informative set of videos. I personally relate to subject because I am personally installing a split unit. I have a strong background in several trades. However, in my 55 years I have shy away from home and car HVAC. You so right about how sloppy the installers are installing a split units. I have turn away several installers because no nitrogen testing and the 500 micron limited reguirdment by the manufacturer. If you ever consider becoming online teacher on HVAC to get a certificate you could sign me up. Thank you again for your time and video. I immensely appreciate for sharing your knowledge. I share the same mamtra, " share the wealth of knowledge with next generation. Your online apprentice.

Good information Terry. I never knew there was so much to know. Well put together vid, impressive as always.

[SteveRobReviews]

Terry I had no idea there was a micron gauge or ever seen one :) Very impressive presentation bud well formatted and you have mastered public speaking as opposed to my jibberish👍 🤣🤣

[cristianpadilla]

Great video, as always. Good to see you again Terry.

[chcou]

Thanks for the great explanation!very well done.

Really a great video on gauges. Thanks

[PhillyPianst]

Great video. You are an excellent teacher. Very clear!

[kennethlobo]

U have a great way of explaining things.Truly admire and thank u for the knowledge u share God Bless from india

[moulaysaidien]

Thanks Terry, great video as always !

I never knew what Torr was, and now I even know who it's in honor of. I learned a lot watching this video today amongst running off to do other things. I really appreciate it. I'm doing very well my friend, how have you been?

[EXOVCDS]

The flat earth remark made me giggle... great informative video as always!
