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

Product Description
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.
