Testo 558s Manifold Gauge 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. Alternatively, the instrument can be operated entirely via the testo Smart App or via buttons for 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 decision even faster. 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. With over 90+ refrigerants stored in the manifold and regular Over-The-Air updates, the manifold is always up to date and ready to accomplish any task.
