Testo 557s Smart Digital Manifold

The testo 557s digital manifold with 4-way valve block enables you to carry out your measurements on refrigeration and air conditioning systems and heat pumps particularly fast. The large display also helps you to evaluate the results in graphic form. Stored programs guide you through the measurement and enable the automatic determination of numerous important system parameters such as superheat, pressure drop test or evacuation. Thanks to the testo 552i Bluetooth vacuum probe included in the kit, the testo 557, as the the first manifold ever, makes wireless vacuum measurement possible. Bluetooth probes for temperature, pressure and humidity can be easily connected directly to the instrument and offer maximum flexibility in their application. In conjunction with the testo Smart App, you can take care of digital documentation directly on site. In addition to this, you always have the current refrigerants available to you, and can set your favourites and transfer them to the instrument. Its proven quality and great durability guarantee the continuously high performance of your manifold in all conditions. FEATURES All results at a glance thanks to the large graphic display. Exceptionally compact and reliable thanks to the easy-to-handle, robust housing with IP 54 protection class. Simple, wireless measurement of vacuum and temperature via automatic Bluetooth connection. Even greater flexibility for your measurements and documentation with the testo Smart App. Even easier to get results, thanks to guided measurement menus for target superheat, vacuum and pressure loss. Convenient refrigerant management in the App with favourites and automatic updates. Can be used for applications with A2L refrigerant, taking into account the relevant legislation, norms and guidelines for refrigeration systems.
