Testo 557 Demo and Review

Check out my demo and review of the Testo 557 digital manifold.
Check superheat and subcooling very easily and quickly. Built in pressure temperature chart for many refrigerants.

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.

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

[alltechclimatizacao]

hi, image sonda pirani testo 557 open?

[nobody]

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

[heleng]

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.

[MrHogzor]

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

[georgewatt]

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

[WillianPortela]

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

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?

[marcusmitchell]

Recently purchased these gauges. They work really well! 💪

[nicholassimpson]

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
