battery. Its robust construction makes it ideal for everyday
use, protected against dirt and water.
testo 552 is the only digital vacuum gauge whose absolute
pressure sensor needs no further servicing, unlike other
sensor technologies.
Suspension device
Fold-out robust hook, making it easy
to attach the testo 552 to pipelines, for
example.
MiniDin connector
MiniDin connector for connection to the
testo 570 digital manifold via connecting
cable (0554 5520).
Battery level display
testo 552 is supplied with two standard AA
batteries with a life of up to 2,400 hours (100
days' continuous operation).
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.

To save, print out or document measurement data electronically, the testo 552 can be connected to the testo 570 with a connecting cable. Long-term
measurements can even be processed over several days without a problem.
