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