Testo 557 Digital Manifold Kit with Bluetooth and Set of 4 Hoses - DISCONTINUED

Testo’s 557 Digital Manifold Kit with Bluetooth was designed for more efficient and precise measurement results. The 557 comes supplied with 4 hoses, each 5 ft long: 3 hoses (blue, red, yellow) with 7/16‘‘ UNF (straight and 45° angle), 1 Hose (yellow) with 5/8‘‘ UNF, (straight and 45° angle) and two temperature clamp probes. The external Pirani gauge allows users to obtain vacuum measurements with the Pirani vacuum probe. Each 557 provides accurate measurements of high and low pressure with the two temperature compensated pressure sensors. Testo has reduced the risk of errors caused my manual calculation with the automatic simultaneous calculation of superheating and sub-cooling. More still, the Testo 557 is built with efficient features and functions like compensated leakage testing, automatic heat pump mode, automatic ambient pressure compensation and more.
