testo 552 - digital vacuum meter
testo 552 is a digital pressure gauge for vacuuming heat pumps and cooling systems. Its robust construction makes it ideal for daily use, protected against dirt and water. The instrument provides very precise information on the degree of dehumidification of a system and the removal of foreign substances (oils, foreign gases, etc.). Since the testo 552 uses an absolute pressure sensor, it is also practically maintenance-free, unlike vacuum gauges with other sensor technologies.
Via a Bluetooth interface, the testo 552 can connect to the testo Smart app on your smartphone or tablet. This makes it possible to monitor the absolute pressure value obtained during vacuum suction - conveniently and wirelessly. In addition, the measurement results can be quickly documented in the app and sent by e-mail.
The testo Smart app requires at least iOS 8.3/Android 4.3.
