Digital refrigeration analyzer - testo 557

With App and Bluetooth.
In a single testo 557 we find a series of essential functions for working in cooling systems and heat pumps. Among others, testo 557 allows the calculation of overheating and undercooling, the measurement of vacuum, the tightness test with temperature compensation. In addition, with the practical smartphone/tablet application, you can supervise the auxiliary assembly unit and store the measurement results or send them by email.

Are you primarily entrusted with the commissioning or maintenance of refrigeration systems or heat pumps? If so, the testo 557 is the ideal digital manifold for you: like the testo 550, this digital manifold replaces multiple tools in the refrigeration industry and can be connected to a practical app. As well as the features of the testo 550 manifold, the testo 557 offers a high-precision external Pirani gauge for vacuum measurement: this enables the quick, safe evacuation of refrigeration systems and heat pumps.

The digital manifold in detail:

Quick, precise measurement of high and low pressure: two temperature-compensated pressure sensors make this possible and automatically calculate the theoretical evaporating and condensing temperature;
Simultaneous calculation of superheating and subcooling: do away with manual calculations, which are time-consuming and during which errors often creep in;
Precise external Pirani gauge for vacuum measurement: you get a high-precision Pirani gauge with the digital manifold, enabling you to carry out accurate vacuum measurement and making it easier to evacuate refrigeration systems and heat pumps;
Two clamp temperature probes included in the delivery: clamp them to the cables to reliably measure the surface temperature;
No need to switch over refrigerant hoses: thanks to automatic heat pump mode;
Can be used for 60 current refrigerants: 60 refrigerants are stored in the manifold, which you can update if necessary via the smartphone/tablet app and adapt to suit your requirements;
Remote monitoring of the measurement: you don't need to stay right next to the manifold during the measurement, you can monitor the measurement from a distance via your smartphone/tablet; coverage of up to 20 m where there are no obstructions (at the very least);
Measurement data display on your smartphone/tablet: your smartphone/tablet displays the readings for you while the measurement is ongoing – really helpful when you are making system settings at the same time;
Practical documentation functions: save your measurement results (in pdf or csv format) and send them directly by e-mail if required. Where applicable, the photos that you took at the measuring location can be appropriately inserted into the documentation using the app;
Refrigerant update: to ensure that the refrigerants in your digital manifold always remain up to date, you can use the app to carry out a refrigerant update.

The app can be used with both Android and iOS systems. After installing the app, manifold and smartphone/tablet can be connected to each other via Bluetooth.
