Testo 552 – digital vacuum gauge
0560 5522
Precise vacuum measurement for cooling and heat pump systems.
The testo 552 is a digital vacuum gauge developed for reliable vacuum suction when installing and servicing 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.
Convenient wireless connection
The testo 552 is easily connected to the testo Smart app on your smartphone or tablet via Bluetooth. There you can:
• monitor pressure values in real time
• document measurement results directly
• share reports conveniently 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 the manufacturer's specifications and ensure correct vacuum suction - every time.
