The testo 552 digital micron gauge is ideal for
monitoring the evacuation of air conditioning,
refrigeration, and heat pump systems. It is rich in
features that make your work faster, easier, and more
accurate.

Precise deep vacuum measurements, measuring down
to single digit resolutions use optimized Pirani sensors.
The testo 552 has real time calculations for the
saturation temperature of water, which determines the
proper micron/temperature levels at which moisture is
removed from the system. These internal calculations

inform you when/if the pressure is low enough to meet
your evacuation target. This saves time and provides
you with the assurance that the system is now free
from moisture and contaminants. User defined alarm
points alert you when target values are reached.

The new testo 552 with Bluetooth links to your smart
phone or device. The testo 552 uses the free testo
SMART Probes App which is a powerful and easy-to­use tool. It allows you to remotely read measurements
of 1 to 6 Smart Probes including the testo 552. You
can easily document / report the results.
