, a 2-way valve block, and a robust hook offering extensive measuring technology in an exceptionally compact format. Use this extremely durable manifold to carry out daily work on refrigeration and air conditioning systems, as well as on heat pumps, wirelessly, with ease and reliability. And all this using the testo Smart App on your smartphone or tablet.

• All results are clearly visible on the large graphic display
• Exceptional compactness and reliability thanks to a convenient and robust casing with IP 54 protection class
• Simple, wireless, and flexible measurements and documentation of results: automatic connection to temperature and vacuum probes via Bluetooth®, the testo Smart App for documentation, and other useful functions.

With this set, you will be immediately ready for the necessary measurements for commissioning, service, and maintenance of refrigeration systems, air conditioning systems, and heat pumps: the set includes the testo 550s digital manifold with a 2-way valve block and Bluetooth, two pipe clamp probes (NTC) with fixed cable, and a robust transport case. Additional Bluetooth probes, for example, for measuring temperature and vacuum, can be ordered separately.

Automatic and precise refrigerant charging according to set superheat, subcooling, and weight thanks to the intelligent valve

Wireless connection and operation with Testo manifolds and the testo Smart App via Bluetooth

All measured values for the charging process at a glance, with measurement data stored in the testo Smart App

Particularly convenient thanks to the compact casing, low weight, practical carrying handle, and robust shoulder bag

Charge refrigeration systems and heat pumps faster, more accurately, and automatically with the testo 560i instrument, the intelligent refrigerant valve, a Testo digital manifold, and/or the testo Smart App. Simply enter the charging program and the target value for superheat, subcooling, or weight into the manifold or App, and the scales and valve will do the rest for you.

Your advantages: time savings and precise system charging.

Fully automated evacuation process with integrated hold test when used in combination with the testo 552i vacuum gauge

Can be safely used even with flammable refrigerants of classes A3 and A2L

One app for everything: configure and monitor measurements, and manage data using the testo Smart App

Easy oil change and sight glass for quick assessment of the oil level

Check valve to prevent vacuum loss in the event of a power cut

Perfect interaction between workflows thanks to full compatibility with the entire Testo range of refrigeration equipment

The Testo 565i dramatically simplifies the evacuation process. Thanks to its smart technology and connection to the testo 552i vacuum gauge, the 565i automatically stops evacuation when the set target value is reached and automatically initiates the vacuum hold check. This means the entire process happens automatically. The Testo 565i has also proven its effectiveness due to its high quality, which allows it to be used safely even with flammable refrigerants of classes A2L and A3.
