Testo 552 – digital vacuum meter

0560 5522

Precise vacuum measurement for cooling and heat pump systems.

The testo 552 is a digital vacuum meter developed for reliable vacuum suction during the installation and service of cooling and heat pump systems. The robust design (IP42 - protected against dirt and water) makes it ideal for daily use even in demanding environments.

The instrument provides very precise information about the system's dehumidification status and the removal of foreign substances such as gases and oils. Thanks to the built-in absolute pressure sensor, the testo 552 is essentially maintenance-free – unlike vacuum gauges with other sensor technology.

Smooth wireless connection

The testo 552 connects easily via Bluetooth to the testo Smart app on your smartphone or tablet. There you can:

• monitor pressure values in real time

• document measurement results directly

• share reports easily via email

(The app requires at least iOS 8.3/Android 4.3.)

With the testo 552 you get a reliable vacuum gauge that makes it easy to follow manufacturer specifications and ensure correct vacuum suction – every time.
