• Fully automated evacuation process with integrated holding test when used in combination with the testo 552i vacuum probe
• Can be safely used even with flammable class A3 and A2L refrigerants
• One app for everything: Configure and monitor measurements and manage data with the testo Smart App
• Easy oil change and sight glass for quick assessment of the oil level
• Non-return valve to prevent loss of vacuum in the event of power failure
• Perfect interaction between workflows thanks to full connectivity to the entire Testo refrigeration portfolio

The testo 565i makes evacuations incredibly easy. Thanks to smart technology and the connection to the testo 552i vacuum probe, the 565i automatically stops evacuation once the desired target value is reached and initiates a vacuum hold test automatically. This means that the entire process takes place all by itself. The testo 565i has also proven its worth thanks to its high quality, which ensures that it can even be used safely with flammable class A2L and A3 refrigerants.
