Testo 558s Digital 4-Way Refrigeration Manifold with Touchscreen – 0564 5581
The Testo 558s is a professional 4-way digital refrigeration manifold designed for commissioning, servicing and fault-finding on air conditioning, refrigeration and heat pump systems.
Featuring a large colour touchscreen, physical keypad controls and Bluetooth connectivity, the 558s gives technicians fast access to pressure, temperature, superheat, subcooling, evacuation and system performance data directly from the manifold or through the Testo Smart App.
The manifold supports A2L and A3 refrigerants and includes more than 96 refrigerants stored in the instrument, making it suitable for modern systems using both traditional and low-GWP refrigerants. Frequently used refrigerants can also be saved as favourites for faster setup.
