The testo 557s digital manifold makes it possible to carry out wireless measurements and digital documentation with its large graphic display. You will receive the testo 557s digital manifold with 4-way valve block, 1 x testo 552i wireless vacuum probe, 2 x testo 115i wireless clamp temperature probes and hose filling set 3x 7/16" UNF and 1x 5/8 UNF. .
Charge refrigeration systems automatically with speed and precision using the testo 560i wireless refrigerant scale, the intelligent refrigerant valve, the testo 557s digital manifold and the testo Smart App. Simply input the charging program, the target value for superheating, subcooling or weight in the app, and let the scale and valve do the rest for you.
Advantages of the testo 557s heat pump all-purpose kit: Carry out your everyday work on heat pumps wirelessly, conveniently and reliably. Thanks to the Bluetooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. All data can be viewed on the large graphic display or on your smartphone or tablet via the testo Smart App.
