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

The Testo 557s Kit 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. It offers reliability, accuracy, and ease of use, enhancing efficiency in all aspects of refrigeration system repair. ... show more

  • 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

  • good but not great for the price.
Style: Basic Kit
Received these gauges Feb 1st 2023, and already have a leaking sight glass I have barely used them (15-20 times) since our AC season in NY has just started to pick up. The range on the Bluetooth is almost laughable too, unless you’re within 20’ of the manifold the second screen mode doesn’t connect. I have always kept them in their hard case or the Veto MB3 bag I keep them in to replace the hard case they came with so they haven’t been abused. Micron gauge and the clamps have worked perfectly fine for me, just a bit disappointed with the manifold itself for the price. ... show more

This didn't work, it wouldn't give accurate temperatures and pressure. Being a tech you can't second guess. Avoid from buying here.
