Testo 552i vacuum gauge

Let’s take a look at Testo’s new vacuum probe. And the testo smart app.

[@ronnyoo9371]

I was told by fieldpiece that in such a small area the deviations are going to be great between pump n probe compared to when u do a whole system because less air movement in the space

[@tcphvacr9950]

I like the new app, with the gauge view. Like that new micron gauge, hope it serves you well 👍🏻👍🏻👍🏻

[@sterlingarcher46]

As soon as I saw the announcement about the new Testo micron gauge I knew I would want one .

[@JoeCdaYT]

Just ordered on of the 552i from Valuetesters for just a little over $161. coming in via fedex. That will be fun to play with for sure when dealing with the small compressor units. Now just have to get one of the Navac units. Already have the smart probes and a 557 manifold, not the 557s. Got the smart probes setup for charging systems with just the one hose.

[@outthemoney3361]

What’s your reasoning for only using it for small compressor units?

[@JoeCdaYT]

@@outthemoney3361 just saying the small ones are fun. I will still be using it on larger systems. I just mostly deal with small units.

[@superiorcomfortheatingairl4636]

Thanks for the Video. It would be great if it shared the other Testo App. If positive pressure is introduced to it does it ruin the Gauge?

[@NorCal-refrigeration]

Great question

[@jphvac5725]

Pretty sure the probes all work on new app same as they did on old one. Really no reason to even keep or use old app anymore.

[@kylebenton8197]

Probably a small air pocket when you valve the pump off, with such a small amount of area under a vacuum it is showing a lot more

[@ReliableHVACR]

Nice. I was worried about the 2cfm but with the right hoses you can pull down quick.

[@rossflores4394]

I just got the new 550 I set So I'm gonna have to add that to the kit now Dave. Thanks

[@christiansommer914]

Got one of those little nuvac good little pump

[@NorCal-refrigeration]

I like it.

[@advancedbasher]

That's a cool pump. I've been using the Testo probes and old app for a bit now but I got the short range Set of 2 clamps and 2 pressure probes and they kind of suck they remind me of the long phone cord on the old land line . I can stand next to the condenser and watch pressures but I cant go in the box and see the pressures or adjust superheat didn't know they have a vacuum probe.

[@NorCal-refrigeration]

Fieldpiece probes have nice range.

[@EverythingHVACR]

I like the vacuum gauge, but think I like the probes rather than the new manifolds. Can the vacuum gauge take positive pressure?

Seems like a pretty good tool ... Good demo Super Dave ... We love the Lurkers ... Lol ...

[@scottk0623]

Is there an advantage to the new app. If your only using smart probes if you don’t have a vacuum gauge?

[@NorCal-refrigeration]

It looks nice.

[@inoahmann7542]

I'm looking forward to seeing it on a system. I have gone through 2 micron guages in 6 months. One was a testo 552 (not a smart probe) and the other was a fieldpiece svg3. The fieldpiece did one install. When I took it off, it still said 370 microns and as far as I know it still does. Idk what keeps killing them, I keep them clean and never exposed either to more than 5 psi. I really want my next micron guage to last.

[@NorCal-refrigeration]

My supco has lasted. My blue vac mini died.

[@captainmigs1655]

Make sure to valve off the micron gauge to make sure refrigerant don’t get the micron sensor

[@inoahmann7542]

@@captainmigs1655 I usually fill the system to 1-2 psi before disconnecting the guage.

[@captainmigs1655]

@@inoahmann7542 if you use the appion vavle core removal T, you can isolate the micron gauge

[@inoahmann7542]

@@captainmigs1655 true, I think I had some oil in my svg3 because I blew it out with some liquid butane and it works again. I just used one of those butane refill tanks and pushed it on one side of the valve core depressor, so it sprayed down into the sensor and carried out any debris or oil that was in there. Butane and propane work great for cleaning hoses, guages, and sensors.

[@gregbowman3598]

Good review Dave👍

[@whitesheatingairappliancer7101]

Thanks for sharing Dave.

[@Rw-gh9hk]

I'm getting down to 9 micron on my jb platinum. But as soon as I valve off the rise is like yours. (just a bit slower) . Where does the testo get it's air temp from?? Built into the 552??

[@NorCal-refrigeration]

No idea

How long does the battery last on the vacuum pump? And how big of a system can be pulled with it?

[@NorCal-refrigeration]

Some guys use it on new AC installs. I use it on prep tables. Get about 30 min per battery. Navac also had 4 cfm pump that’s battery powered.

[@coldfinger459sub0]

Ball valves on vacuum pumps were never meant for holding deep vacuum. Good enough to stop air from sucking back in the system and good enough to stop oil from being sucked out of the vacuum pump into the system.

Same difference.

It is a vacuum guage because it doesn't only measure in microns.
