The Testo 550S digital manifold kit provides accurate tools for measurement on refrigeration, air conditioning systems, and heat pumps. Stored programs in the manifold guide the user through measurements and enable the automatic determination of numerous important system parameters such as superheating/subcooling, target superheat, cooling/heating capacity and many other areas. Bluetooth probes for temperature, vacuum, and humidity can be connected and provide flexibility in their application. In conjunction with the Testo Smart App, the user can easily create digital documentation on site.
**PLEASE NOTE: The Testo Smart App currently runs on iOS 11.0 (or newer), and Android 6.0 (or newer)**
