Nice video. Just bought a used unit on eBay. I was the winning bidder and got it for $203 and $15 shipping. Great price compared to a new unit. I turned it on and everything seems to be working. Lots of snow outside so will have to wait till it gets warmer to check out the gauges on my heat pump. Thumbs up on your video.

[@alexandersalas268]

Digital is good one but problem is under the sun hard to see display .

[@clevc112]

Starting school in February. Soon as we need gauges I'm buying this.

[@murkyturkey5238]

I would start with analog, it will help you understand and learn more

[@murkyturkey5238]

Guess I’m a little late here 😂

[@MrLuchoBigoton]

Great video I only have one problem and it's that I've have problems using the vacuum prove if you can help me out! Thanks again

[@jhint190]

Good info video! Should do one using the vacuum probe

[@HVACKnowItAll]

Jeremy Hinton thanks, I did one the other day, my most recent video on my channel...it's not you typical vacuum vid, have a look, you'll see!

[@WillianPortela]

Greatings from Brazil! testo 557 its a amazing manifold. where you buy the black hose on low side?

[@HVACKnowItAll]

Willian Portela it's actually blue, bought it in Toronto!

[@nicholassimpson8649]

just made the switch from field piece to testo. meter and gauges. only had issues with running a vacuum I figured out I need a Schrader core tool or a T for 3 connections, for my micron gauge and doing the leak search mode i havent figured out i got to the mode but not sure whats going on. subscribed and liked on FB. If you could make videos about that. would be great I figured out everything you showed in this video. any additional tips would be great

[@MrRohanstar]

Can i use it on cars

[@stephenmanning7627]

[@scottvanruin6481]

High Subcooling Low Suction Pressure, normal SH, overcharged and underfeeding TXV?

[@cranium33333]

Scott van Ruin Or false reading because he’s hood to discharge line not liquid line with his high side hose.

[@heleng4528]

Do you still use these? I'm a first year apprentice and am looking for a set to as back up for my analogs. I can't choose between the sman380 and these.

[@HVACKnowItAll]

Yes I do, they've been awesome. Your analogs will become your back up after using them

[@heleng4528]

@@HVACKnowItAll 😅 thank you. I really like that the testo gauges are low profile.

[@oby-1607]

I am looking at a testo 557 that is used. It has a small crack in the bottom right of the display. It is also missing the vacuum pickup. He wants $375 for it but it is unproven yet. It also comes with the case and one red hose and one yellow. It also powers up when the power button is pressed. What do you think?

[@HVACKnowItAll]

375 seems much for a cracked screen, what if it gets worse?

[@oby-1607]

@@HVACKnowItAll Thats what I'm thinking. Maybe I am better getting it online.

[@HVACKnowItAll]

If you do I have a discount link for trutech tools for preferred testo pricing. www.bit.ly/TTT-DISCOUNTS, just make you sure you tell them hvac know it all sent you

[@nobody94820]

Can it vaccum past 500 microns? Is it like fieldpiece where it will change into microns on the display ?

[@georgewatt1580]

What's the difference between these and the 550? Besides a 4th hose

[@HVACKnowItAll]

557 comes with a vac gauge and perhaps 550 may not be bluetooth compatible, but cant remember

[@MrHogzor]

will get some time getting use to. how will i do manual depressurise? for ovveriding the unit?

[@HVACKnowItAll]

MrHogzor I'm not sure what that means!

[@stephwaylonwells3218]

[@dfigueroa903]

Can the 557 work with wireless testo t probes?????

[@MrCrunchyEGGROLL]

How do you like this Testo 557 comparing to the Fieldpiece SM380V?

[@HVACKnowItAll]

Love them, haven't tried Fieldpiece

[@alltechclimatizacao580]

hi, image sonda pirani testo 557 open?

[@hangngoaigiare]

I don’t know why they don’t make them temp probes Bluetooth. Those probe so weak they go bad fast.

[@HVACKnowItAll]

Only a matter of time

[@hangngoaigiare]

Ya they have all the technology they need to make that. We need to push them. Those temp probe $50 a piece not cheap.

[@Akvan79]

Does your have the Bluetooth feature?

[@HVACKnowItAll]

yes!

Why am I just finding your stuff?

[@HVACKnowItAll]

Stephen Rardon I justed launched this project on social media in September of last year...I started on Facebook, now on Instagram, LinkedIn, Twitter and obviously KZbin. I had never made videos before. But from my first to my latest, I'm slowly getting better! I've heard your name out there on a few occasions...Nice to meet, my name is Gary McCreadie btw....not really a know it all, just a catchy name for web!

[@EternalMaster12]

I bought a used testo 557. looks different than ones I see online. it does not have the opening on top either. can it be a fake?

[@HVACKnowItAll]

Cesar Gonzalez maybe but I've never seen knock offs

[@MrDjmurdock]

I have the one you have not fake the video is just a newer model

[@EternalMaster12]

Oh, thank you

[@ACXR6]

can you do a demo video for evacuation with the testo 557?

[@HVACKnowItAll]
