Product Description

Are you responsible for the commissioning or maintenance of air conditioning and refrigeration systems, as well as heat pumps? If so, the testo 557 is the ideal digital manifold for you: this digital manifold replaces multiple tools in the air conditioning and refrigeration industry and can be connected to testo’s powerful Refrigeration App. The testo 557 offers a high-precision external Pirani probe for vacuum measurement: this enables the quick, safe evacuation of refrigeration systems and heat pumps.

State-of-the-art technology creates easy work: the digital manifold kit in detail

The testo 557 four valve digital manifold was developed to lighten your workload, organize your working time more efficiently and to deliver more accurate measurement results – as well as to offer your customers even more reliable service. See all the advantages at a glance:

Quick, precise measurement of high and low pressure: two temperature-compensated pressure sensors make this possible and automatically calculate the evaporation and condensation temperature
Simultaneous calculation of superheating and subcooling: do away with manual calculations, which are time-consuming and prevent errors where they could often occur
Including 4 hoses, each 5 ft long: 3 hoses (blue, red, yellow) with 1/4‘‘ SAE (straight and 45° angle), 1 Hose (yellow) with 3/8‘‘ SAE, (straight and 45° angle), suitable for all refrigerants
Precise external Pirani gauge for vacuum measurement: you get a high-precision Pirani vacuum probe 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 scope of delivery: clamp them to the pipes to reliably measure the surface temperature
No need to switch over refrigerant hoses: switching is superfluous 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 Refrigeration App and adapt to suit your requirements

Other key functions of the 4-valve manifold are temperature-compensated leakage testing and automatic ambient pressure compensation.

Manifold with powerful App: connect the measuring instrument to your smartphone/tablet!

You can download the Refrigeration App for the testo 557 digital manifold onto your smartphone or tablet. The App will make your work easier thanks to its wide range of smart functions:

Remote monitoring of the measurement: you don't need to stay right next to the manifold during the measurement, instead you can monitor the measurement from a distance via your smartphone/tablet; coverage of up to 60 ft with no obstructions
Measurement data display directly on your smartphone/tablet: your smartphone/tablet displays the readings for you while the measurement is ongoing – this is really helpful when you are making system adjustments at the same time
Practical documentation: 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, the manifold and smartphone/tablet can be connected to each other via Bluetooth.

Innovative technology in one robust package

A sturdy housing reliably protects the testo 557 digital manifold from impacts (according to protection class IP 42). Thanks to the suspension hook on the back, the instrument is well-secured during the measuring process. The illuminated display ensures optimum legibility of the readings, even if visibility is poor.
