Digital manifold testo 550 – the Bluetooth manifold for refrigeration systems and heat pumps App integration via Bluetooth for fast and convenient monitoring and reporting on site Refrigerant update in the instrument via App Calculation of superheating/subcooling in real time with up to two external temperature probes 2-way valve block with three connections, three hose parkers and sight glass 250 hours' battery life MPa The new testo 550 is the robust tool for daily work on to be updated, for example. The more robust housing, with refrigeration systems and heat pumps. The robust 2-way a metal frame around the display, protects the new testo metal valve block with 3 connections and 3 hose parkers 550 even more reliably from impact. The vacuum display allows you to work quickly and easily. indicates the level of vacuum reached in evacuation. The The App integration via Bluetooth opens up new testo 550 is thus excellently suitable for commissioning, possibilities for efficient analysis and documentation. Via service and maintenance. Thanks to additional features the wireless connection, users can read off the such as the automatic heat pump mode, which eliminates measurement data on a Smartphone or tablet, allowing the need to switch over the hoses, and the temperature- them to work more quickly and conveniently. In addition to compensated tightness test function, working on this, the user can finalize and send the measurement report refrigeration systems and heat pumps is easier than ever directly on site. The App alows the list of stored refrigerants
