The Testo 552 is a digital vacuum gauge for the precise measurement of extremely small pressures in the vacuum range. This allows you to monitor the evacuation (usually during commissioning) of refrigeration systems and heat pumps.
With the Testo 552, you can therefore measure the current pressure in a refrigeration system, and thus gather information about the degree of dehumidification and the removal of foreign matter (oils, foreign gases, etc.). A vacuum gauge is always used in conjunction with a vacuum pump (generates the vacuum). A manifold (analogue or digital) is also often used in order to obtain controlled access to the refrigeration system.
In addition to the above, the new version of the Testo 552 connects via Bluetooth with the testo Smart Probes App on your smartphone or tablet. This allows you to monitor the absolute pressure reached during the evacuation and measurement results are documented in the App and sent by e-mail report.
The Testo 552 is the only digital vacuum measuring instrument whose absolute pressure sensor, in contrast to other sensor technologies, no longer needs to be serviced, and still provides highly accurate measurement results.
Fold-out robust hook suspension device.
MiniDin connector for connection to the Testo 570 digital manifold via connecting cable.
Battery level display - supplied with two standard AA batteries with a life of up to 2,400 hours.
Temperatures - Evaporation temperature of water (H2O), ambient temperature and the temperature difference DeltaT are displayed.
Absolute pressure - Clear display of the absolute pressure value measured.
Display illumination makes it easy to read off the data, even in dark surroundings.
