The Testo 557 4 valve digital manifold includes a set of 4 hoses and bluetooth to provide HVAC technicians with an all in one tool to measure temperature, high side / low side pressures, and vacuum. Download the free Testo refrigeration app to monitor your HVAC/R system and generate reports for customers.

Key Features:

  • Measures Temperature from -58 to 302 °F (-50 to 150 °C)
  • Measures High and Low side Pressure -14.7 to 870 psi (-1 to 60 bar)
  • Measures Vacuum with external Pirani sensor (0 to 20,000 Micron)
  • Includes a set of 4 60 inch refrigeration hoses
  • Couples with the Refrigeration App via Bluetooth


Transitioning from a traditional analog manifold gauge to a digital version is one of the most cost effective ways to improve work efficiency that translates to more money in your pocket. The Testo 557 4 Valve manifold lets you hook up to an HVAC/R and heat pump systems and monitor it in real time from your phone or tablet. This frees you up to work on other areas of the job site or head back to the truck to start your paperwork.

The two provided temperature clamps allow you to see automatic calculations of superheat and subcooling. The pressure connections are 1/4" ports and the monitor displays both the high and low side pressures simultaneously.

Included in the Testo 557 HVAC Manifold is an external Pirani gauge that makes it easier to take precise vacuum measurements on refrigeration systems and heat pumps.

The hoses that come with this kit are all 5 feet long (60 inches) with three hoses (Red, Blue, Yellow) having a 7/16" UNF connection (straight and 45° angle) and a second yellow hose having a 5/8" UNF connection (straight and 45° angle) that can be used with all refrigerants.

One of the best reasons to buy a digital manifold is the large refrigerant profile database. Gone are the days of having to know what specific freon you were working on so you could grab the correct vacuum gauges out of the truck. The Testo 557 includes 60 refrigerant profiles out of the box and can be updated via the refrigeration app when new freons are created.


The Testo 0563 2557 includes the following components:

  • 557 digital manifold with Bluetooth
  • Temperature clamp probes (Qty 2)
  • External Pirani Vacuum Gauge with cord
  • Set of (4) 60" refrigeration hoses
  • Batteries
  • Carrying Case
  • Certificate of Conformity
