      Control and read complete measurement via smartphone

    Precise deep vacuum measurements measured at single digit resolutions are carried out with Pirani sensors. The testo 552 provides 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 the pressure is low enough to meet your evacuation target. This saves you time, and assures that the system is now free from moisture and contaminants. User defined alarm points alert you when target values are reached.
    The new and improved testo 552 with Bluetooth links to your smartphone or device, and to the free testo Smart app.

    Complying with manufacturer's specifications

    Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.

    Connect to the testo 570 Digital Manifold

    When you connect the testo 552 Digital Vacuum Gauge to the testo 570 Digital Manifold, you can save the testo 552's readings directly on a laptop via the optional EasyKool software. This allows data-logging and/or on-site printing.

    Complying with manufacturer's specifications

    Some manufacturers specify the desired micron lower limit that must be achieved to evacuate their air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.

    Evacuating AC/R systems

    The testo 552 Digital Vacuum Gauge is for the evacuation of heat pumps, air conditioning, and refrigeration systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Never worry about a dirty sensor causing false readings. Trust your testo 552 to always be accurate.
