The Testo 558s (0564 5581 01) 4-Valve Digital Manifold provides users with a dynamic view of trending data in the palm of their hands. Interpreting data is even more important to ensuring an efficient refrigeration system with today's standards. Touchscreen operation makes configuration, control, and documentation even easier as well. Alternatively, the instrument can be operated entirely via the Testo Smart App or via the buttons while working with gloves. To make everyday work even easier, the measurement results can be shown on a large color display in clear graphs as 30-minute data trends to make critical diagnostic decisions even faster.

The high measuring pressure accuracy of 0.25% full scale enables quick and reliable measurements and supports getting the job done efficiently in order to limit the amount of call backs from customers. Due to the large number of stored measurement menus and connectivity across the entire Testo refrigeration portfolio, any application can be controlled via the manifold.

For added safety, the manifold is compatible with flammable class A2L and A3 refrigerants. With over 90 refrigerants stored in the manifold and regular over-the-air updates, the 558s is always up-to-date and ready to accomplish any task.
