testo 552 is a digital vacuum gauge for the evacuation of
refrigeration systems and heat pumps. It measures even the
smallest absolute pressures, and delivers highly accurate
information about a system's status of dehumidification
(removal of foreign matter, incl. oils, foreign gases, etc.).
Via a Bluetooth interface, the testo 552 connects with the
testo Smart Probes App on your smartphone or tablet. This
allows you to monitor the absolute pressure reached during
the evacuation conveniently and wirelessly. In addition to
this, the measurement results can be quickly documented in
the App and sent by e-mail.
Its robust construction makes it ideal for everyday use,
protected against dirt and water
