Electronic Vacuum Meter Testo 552
Testo
Electronic Vacuum Meter Testo 552
Art. no.: 7066456
Testo 552 is a digital vacuum reader for vacuum suction of cooling systems and heat pumps. It measures very low absolute pressure values and provides extremely accurate information about the system's dehumidification status (removal of foreign matter, including oils, foreign gas, etc.). Via a Bluetooth interface, testo 552 can connect to the testo SmartProbes app on your smartphone or tablet. It allows monitoring of the absolute pressure value obtained during vacuum suction - conveniently and wirelessly. In addition, measurement results can be quickly documented in the app and sent by email. The robust construction makes it ideal for everyday use and protects it from dirt and water.
Battery time: 50 hours without Bluetooth / backlight)
Compatibility for the SmartProbes app requires iOS 8.3 or later / Android 4.3 or later. It also requires a mobile device with Bluetooth 4.0
Vacuum Pump Class A1, A2, A2L & A3
Testo
Vacuum Pump Class A1, A2, A2L & A3
Art. no.: 75897865
The new testo 565i vacuum pump performs vacuum extraction of refrigeration systems and heat pumps completely automatically thanks to the connection to the testo 552i vacuum sensor. When the desired vacuum target value is reached, the pumping stops automatically and a vacuum hold test starts simultaneously. This safely removes foreign gases and moisture, and information about the system's tightness is saved. The data logging function ensures complete documentation. This allows vacuum extractions to be carried out entirely independently.

Configuration, monitoring of real-time values, and sending of measurement reports can be easily managed via the free testo Smart App. This makes you flexible and saves valuable time.

For an optimal workflow, the testo 565i automatically establishes a Bluetooth connection to Testo's refrigeration gauges and to the testo Smart App when it is started. The pump also guarantees maximum safety at all times thanks to its compatibility with A2L and A3 refrigerants.

The testo Smart App guides you quickly and easily through measurements on refrigeration, air conditioning, and heating systems.
