Buy Now →The testo 558s is a digital manifold with a 4-way valve block and a capacitive color touchscreen for commissioning, servicing, and maintaining refrigeration systems, air conditioning systems, and heat pumps. It can be operated by touchscreen, by physical keypad for gloved hands, or entirely via the testo Smart App, and it shows 30-minute data trend graphs on screen. It measures pressure from -14.7 to 870 psi at plus or minus 0.25 percent full scale, the highest accuracy in the s-series, and temperature from -58 to 302 F via two plug-in NTC probes. It is the direct replacement for the discontinued testo 557s and is A2L and A3 refrigerant compatible. It uses a hybrid power system with a built-in USB-C rechargeable Li 18650 battery plus three replaceable AA cells. Vacuum is read by the wireless testo 552i probe; the manifold has no integrated vacuum sensor. It connects directly to measureQuick over Bluetooth 5.0. It also pairs with wireless probes and the testo Smart App.
