testo 557s Smart Vacuum Kit - Smart digital manifold with wireless vacuum and clamp temperature probes

0564 5571

Completely wireless measurements and all results at a glance: thanks to Bluetooth probes and large graphic display

Exceptionally compact and reliable thanks to the easy-to-handle, robust housing with IP 54 protection class

Easy, wireless, flexible measurements and documentation: Temperature and vacuum measurements via automatic Bluetooth^® connection, testo Smart App for documentation and lots more

A3 and A2L compatible and over 90 stored refrigerants

Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. Thanks to the Bluetooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, one testo 552i wireless vacuum probe (Bluetooth), two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. For other wireless measurements, other optionally available testo Smart Probes are also ideal.
