  • Testo 557s has been a valuable addition to my toolkit as a refrigeration system repair technician.

The digital manifold with app connectivity simplifies data readings, making my job much easier. The accuracy of the two 115i pipe clamp thermometers is impressive, providing reliable temperature measurements critical for diagnosing and repairing refrigeration systems. The 552i micron gauge is a standout feature for its precision in vacuum measurements, essential for ensuring system integrity and detecting leaks. The robust build quality of the tools in the kit withstands the rigorous demands of refrigeration repair work. Bluetooth connectivity is a huge plus, allowing me to monitor and record data on my smartphone, which is incredibly convenient for tracking repairs and maintaining accurate service records. In summary, the Testo 557s Kit is a highly recommended tool for any refrigeration technician.

  • Took 3 Times But Finally a Good One
Style: Vacuum Kit with 4 Hoses
This is a great set! Has all the options you need in a manifold set. I compared the Mastercool but it reflected the price difference in quality. I looked at the more expensive fieldpiece but Testo was a little less. Took me three times to get a good one. The first one I ordered was an opened box item. Supposed to be complete, just a damaged box. It showed up without the hoses. The second one I ordered showed up in a box in a box with an old shipping label cut off the inside box. Made me think it was previously returned as well. Didn’t keep it. The third one I ordered appears to be the real deal. ... show more

  • Great gauges junk hoses included
Style: Vacuum Kit with 4 Hoses
I have been using the gauges for a week now and so far so good works perfectly. The reason for the 4 stars is because I bought the testo that included the hoses.... complete JUNK! All 3 of the gaskets had blown out of the hoses in the first day and I had to put on my old hoses... they are no name brand junk. Buy the gauge and buy a set of yellow jacket or JB hoses separately and you will have a great setup. Why they included junk with a 650$ manifold is beyond me. Wish I could get a refund ... show more

  • Vac FAILS decay test. Avoid this item!
Style: Basic Kit
The Testo 552i handles a vac of about 23 microns ok, but it is horrible for a decay test. When testing the unit with a brand new Appion core removal tool and directly hooked with the pump. The unit LEAKS bad. I DO NOT RECOMMEND THIS UNIT.
