Features

  • VERSATILE; The vacuum gauge replaces multiple HVAC gauges and was developed to deliver extremely precise temperature, pressure, and vacuum measurements on refrigerant systems and heat pumps
  • USER-FRIENDLY; With its intuitive menu, 4-way valve block and automated probe connection, the manometer provides convenient pressure measurement in areas that are difficult to access
  • WIDE RANGE; The micron gauge offers reliable temperature measuring range of -58 to 302 F / -50 to +150 C, pressure measuring range of -15 to 870 psi / -1 to 60 bar, and vacuum measuring range of 0 to 20000 micron
  • PRECISE; Thanks to the sensitive sensors, the vacuum gauge provides temperature accuracy of +-0.9 F / +-0.5 C, pressure measurement accuracy +-0.5 % of full-scale value, and vacuum measurement accuracy +- (10 micron + 10 % of mv) (100 to 1000 micron)
  • COMPATIBILITY; The hvac multimeter can be used for 60 refrigerants on the instrument and updated via App if necessary. Compatible refrigerant instruments are but not limited to R114; R12; R123; R1233zd; R1234yf; R1234ze; R124; R125; R13; R134a; R22; R23; R290; R32; R401A; R401B; R402A; R402B; R404A; R407A; R407C; R407F; R407H; R408A; R409A; R410A; R414B; R416A; R420A; R421A; R421B; R422B; R422C; R422D; R424A; R427A; R438A; R437A; R442A; R444B; R448A; R450A; R449A; R453a; R452A; R454A; R454B; R455A; R454C; R458A; R502; R500; R503; R507; R718 (H2O); R600a; R513A; R744 (CO2)

    • Took 3 Times But Finally a Good One
Style: Vacuum Kit with 4 Hoses Pattern Name: Thermometer
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

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

    • good but not great for the price.
Style: Basic Kit Pattern Name: Thermometer
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

    • Not their best product
Style: Vacuum Kit with 4 Hoses Pattern Name: Thermometer
All hoses failed within 30 days. They have the plastic seals on them. Sucks when you’re on an overnight job and 2 of your hoses break seal. Customer support was unhelpful. Hours on hold and being transferred between Amazon and the manufacturer got me no where. So much for the 90 day guarantee. The micron gauge doesn’t really work that great. It can help with diagnosis but not with pulling a vacuum. Constant updates. Literally every time I bring this out (almost daily) there is some sort of update for the device or phone app that takes forever and completely resets the system so you have to just bypass it unless you want to spend an extra 2 hours on a hot rooftop. They’ve got some work to do with the technology. ... show more
