Identify vacuum quickly and easily by means of the graphical display in the App or on the digital manifold screen
Connects automatically via Bluetooth® to the testo Smart App and digital manifolds
Exceptionally compact and reliable thanks to the rugged, easy-to-handle housing with IP 54 protection class
Easy installation at any service port thanks to the integrated 45° angle
Use the testo 552i vacuum probe with Bluetooth to measure vacuum wirelessly with speed, ease and precision via just one service port – with no loss of refrigerant. The testo Smart App supports you with numerous intelligent features – for example, you can see the vacuum by simply glancing at the graphic illustration in the app or on the manifold’s display. Thanks to its robust, convenient housing and proven measuring technology, the vacuum probe is compact and reliable when carrying out your vacuum measurements on refrigeration and air conditioning systems and heat pumps.
Wireless vacuum measurements via just one service port: The testo 552i app-controlled vacuum probe with Bluetooth enhances the Testo Smart Probes portfolio. It delivers reliable measurement results, is robust and easy to use – the vacuum probe provides optimum support for proper evacuation of refrigeration and air conditioning systems and heat pumps.
testo 552i - App-controlled wireless vacuum probe
For wireless, hose-free vacuum measurements on refrigeration and air conditioning systems and heat pumps using just only one service port – with no loss of refrigerant
testo Smart App – get an overview of everything: Detect vacuum quickly and easily via a graphic illustration in the app, with an alert in the event of any critical values, e.g. through vibration of the smartphone
Automatic connection via Bluetooth: The probe connects to the testo Smart App or to the appropriate digital manifold from Testo, e.g. testo 557s, testo 550s – so you can also read measured values conveniently on your manifold’s large display
Convenient, robust housing with protection class IP 54
Built-in 45° angle for easy installation at any service port
Continuously high performance in all conditions: You can depend on this wireless vacuum probe from Testo – it combines proven Testo quality with excellent robustness
App-controlled testo 552i wireless vacuum probe, including batteries and calibration protocol.
Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Connect to the testo 570 Digital Manifold
When you connect the testo 552 Digital Vacuum Gauge to the testo 570 Digital Manifold, you can save the testo 552's readings directly on a laptop via the optional EasyKool software. This allows data-logging and/or on-site printing.
Complying with manufacturer's specifications
Some manufacturers specify the desired micron lower limit that must be achieved to evacuate their air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Evacuating AC/R systems
The testo 552 Digital Vacuum Gauge is for the evacuation of heat pumps, air conditioning, and refrigeration systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Never worry about a dirty sensor causing false readings. Trust your testo 552 to always be accurate.
