Testo 557s Smart Vacuum Kit with Filling Hoses
Brand: Testo
For completely wireless measurements on refrigeration and air conditioning systems and heat pumps.
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), a hose filling set with 4 hoses and a robust transport case.
For other wireless measurements, the Testo Smart Probes are ideal.
Features- 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®
