Testo 558s Smart Digital Manifold
The digital manifold with 4-way valve block and intuitive touchscreen
Providing a dynamic view of trending data in the palm of your hand – that’s where digital manifold testo 558s excels. 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.

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 decision even faster.
The high measuring pressure accuracy of 0.25 % full scale enables quick and reliable measurements supports getting the job done efficiently and limiting call backs. Thanks 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 maximum safety, the manifold is compatible with flammable class A2L and A3 refrigerants.
