Testo 552 Vacuum gauge
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.
