The electronic testo 550 valve housing is a must for everyday refrigeration and heat pump installers. The robust 2-way valve battery allows for quick and convenient measurements. The integrated mobile application opens up new possibilities for the user and allows for efficient analysis and documentation of the data at the measurement site. The Bluetooth included in the kit allows the service technician to read measurement results on the smartphone and tablet, making the job even easier. In addition, the user can prepare and send the report directly from the place where the measurement was made.
By using a mobile application you can manually update the list of supported refrigerants without the factory service approval. The reinforced housing with a metal frame around the display protects the testo 550 against damage. The testo 550 is perfect for starting, servicing and maintaining refrigeration systems. With additional features such as the heat pump mode, which eliminates the need for hose switching and the tightness compensation function with temperature compensation, cooling and heat pump operation is even simpler.
