The testo 552 is a digital vacuum measuring instrument for the
evacuation of refrigeration systems and heat pumps. It measures even the
smallest absolute pressures and provides highly precise information on
the status of the dehumidification of a system (removal of foreign
substances, incl. oils or foreign gases). Its robust construction makes
it suitable for daily use, and protects from dirt and water.
In addition to the above, the new version of the testo 552 connects
via Bluetooth with the testo Smart Probes App on your smartphone or
tablet. This allows you to monitor the absolute pressure reached during
the evacuation and measurement results are documented in the App and
sent by e-mail report.
