The Testo 557 Digital 4-Way Manifold was developed to relieve your workload, to make your work more efficient, and to deliver more accurate measurement results as well as to offer your customers services that are even more reliable. It offers a high-precision external Pirani gauge for vacuum measurement. This enables the quick, safe evacuation of refrigeration systems and heat pumps.

The Testo 557 Digital Manifold fulfills numerous functions, which are required for working on refrigeration systems and heat pumps, in just one instrument like superheating/subcooling calculation, vacuum measurement, temperature-compensated leakage test. You can also use a practical app to monitor the manifold via your smartphone/tablet and store the measurement results or send them by e-mail.
