CPS VG200 Micron Gauge Review

I got a new toy!
In this video I tear down, review and explain how the CPS VG200 vacrometer/micron gauge works.

F-ing awesome,thanks for opening it and explaining the inner workings

[@shaunirwin4129]

Great video, very informative. You really know your stuff. Thanks!

[@TheGibby3340]

Great video. Very well explained indeed. Thx & Cheers 👍

[@jaysherlock7307]

Hi great video, I have a this gauge. I'm unable to get it out of low battery mode. Just shows dotted lines and a empty battery indicator. put a new battery in and cleaned the sensor with alcohol. Still the same.

[@akaixl83]

My fav micron gauge by far, I’ve owned 3. I use them for about 3 years then resell and buy a new one, I always keep them in the case and clean with alcohol every 5 vacuums

[@osos231]

Where are the CPS gauges made?

[@parker12c]

I can't get this POS to pair with my phone lol and the cps link app is dog shit

[@Jonathan-gz6tu]

​@@osos231it says made in the USA on the front, top right

[@jonathanb3407]

Mine only shows 2 digits on the micron screen. All the digits work when your scrolling through the different readings. Not sure what’s wrong with it.

[@ScarecrowI]

Hi while this video was very informative, i am here to ask about the raspi video you made a few years back setting up a touch screen, (comments closed on video) i cant seem to get the calibration to work, while in your video you touched on the marks almost perfectly, my mouse doesnt seem to registor this very well.

[@ryanbaik9217]

Hello thanks for sharing What vacuum pump are you using? Looks compact and light

[@NearFarMedia]

It's a Tasco brand (A Japanese brand) TA150SB-2. It works quite well.

[@b-2466]

I'm new to hvac.. if I have the fieldpiece SMAN 380V manifold would I even need the CPS vacuum gauge? I have both already that's why I'm asking.

[@NearFarMedia]

I'm not familiar with the SMAN, you'd have to check if it has a micron gauge function built in.

[@luis2012174]

Hello ,can you tell me why is my cps micron gauge is turning off by itself while is working with the vacuum?

[@NearFarMedia]

It has an automatic timeout to turn itself off after 5 minutes so the batteries don't run flat. It happens to me too, so I just turn it on again. There doesn't seem to be a way to disable the automatic shutoff unfortunately, so you'll just have to turn it back on when it turns itself off..

[@jet6374]

why did you smack your gage???

[@scsclassics]

Where does this leak?? Everyone says that they leak mine doesnt .just trying to get an idea if it does happen thanks .

[@NearFarMedia]

Mine works fine and doesn't leak at all. I think if you are careful and take care of it, it will work for years without leaking.

[@Trigger_32]

Mine leaks brand new out of the box, on the first evac. Was hoping he was gonna break down the connection side of it as well. Guess ill have to do it… seeing as my Amazon return window is closed. I also have an email to CPS about it. Lots of reviews on Amazon stating the same.

[@factotumted]

Got mine today and it was bad out of the package ☹️

[@Amerikanin2numarali_ustasi]

what kind of vacuum PUMP is that? do you share make/model?

[@NearFarMedia]

It's a slightly older Tasco brand pump, a popular Japanese brand. They don't make this one anymore it seems but you can see their catalogue here: www.tasco-digitalcatalog.com/2022/#target/page_no=72 Here it is, in English: www.tascojapan.co.jp/en/product.php?prc=detail&sid=3 And an English catalogue: www.tasco-digitalcatalog.com/e_2021/#target/page_no=23

[@emericaki27]

Do you know how many decimal places this measures to in inches of mercury?

[@NearFarMedia]

I just checked now, it measures to three decimal points on the Inches of Mercury range.

[@emericaki27]

@@NearFarMedia very much appreciated! The Boeing Company thanks you for you.

[@Kntryhart]

Great info, but which way does the battery get installed?

[@NearFarMedia]

The battery should only be able to go in one way, but the +ve terminal of the 9V battery goes to the top connection.

[@Kntryhart]

@@NearFarMedia Thanks! After I posted that question, I found that if I looked into where the terminals were mounted, I could see a red and black wire. Thanks again!

[@WilliamVG]

What's the life expectancy of these gauges? During rugged everyday use, will these last a few years in service?

[@NearFarMedia]

They should easily last for many years as long as you take care of it and don't let the battery leak inside. There are no wear parts, basically the only maintenance needed is an occasional wash with isopropyl alcohol inside the pipe fitting where the sensor sits.

[@pwrouzaud]

I've got the same vacuum gauge. You mentioned, "if it stabilized above 3000" be looking for issues. Why that figure 3000? Does this mean, at that level of vacuum it is unlikely to be a leak in the pipe, and more likely to be off gassing, etc? Signed: Inexperienced

[@NearFarMedia]

3000 micron means a good enough vacuum for aircon applications. Lower is always better though. If it slowly rises, you need to check for leaks as air is getting in somewhere. I can routinely get down to the low hundreds on a new install, getting around or even under 500 micron shouldn't bee too hard, so it's always good practice to let the vacuum pump run for half an hour or so to make sure you have as much of the air out as possible.

[@johnjenkins3342]

@@NearFarMedia i dont know if youve actually done an ac cert but youre microns arent meant to rise above 600...

[@1989Chrisc]

@@NearFarMedia 3000??? Its 500 or lower.. I usually dont charge larger systems until I get 300

[@Kevin-ib4gv]

3000 is too high. Holding at 500 is great. 1000 or below you're good. 1000 to 2000 means condensables, (air, gases) moisture, or even a small leak. Evacuate again and/or fix small leak. Above 2000, definite leak. All micron gauges will rise after pump is turned off because of the power of the pump is pulling down on the vacuum. Once that vacuum action is cancelled, (pump off) there is just that much LESS pulling vacuum and the microns increase. Other factors apply as well as he stated, but remember you are in microns which is a very small unit of measurement. This is why it's used to check for leaks as even the tiniest leak will show up causing microns to increase.

[@lancetyrell7575]

Go for 300 micron if it's goes up back to 500 micron that's good. 3000 is way to high

[@ghostridergr8259]

nice video... tell all the others testo 552 not leaking....hahahaha its normal .....that effects... exept if you use metal pipes clean and Strong

[@petti78]

Is that chinese ebay gear you bought or actually usable ones? And one can only roll eyes about the whole cost thing... Things really are cheaper than people.

[@NearFarMedia]

+petti78 You mean the VG200? It's a genuine tool from America. No fakes in this video! :)

[@flip2724]

On the site *n.*an*.sh*p it says the vacuum pump is a toe stage vacuum pump ha

[@ghostridergr8259]

and one other things this tools its very sensitive... and 100 micro or 200 its nothing when rise again... even when you close the valve we lost Ballance in sircuit and some gas gos back...

[@kerrodmartorella4949]

another sparky playing fridgy haha

[@NearFarMedia]

Uh-oh, I've been found out! :D haha

[@brycelawmaster3746]

3000 lol. youre obviously not an ac tech.

[@NearFarMedia]

Yeah, one zero too much..... I usually pump down to 250-300 micron and let it sit for 10 minutes to make sure it stays there.
