Testo 557 Digital Manifold


The digital manifold testo 557 is a robust tool for all measurements on a refrigeration system or a heat pump.

The manifold disposes of a robust 4-way metal valve block with additional connection options, for example for a vacuum pump or refrigerant bottle. This provides a definite advantage in the handling and enables fast and efficient service, maintenance and commissioning.

The solid housing reliably protects the testo 557 against any strain in everyday work. The integrated vacuum measurement enables reliable measurement results when evacuating refrigeration systems and heat pumps. Especially the automatic heat pump mode, which makes switching over the refrigerant hoses superfluous, the temperature-compensated tightness test function and the automatic ambient pressure compensation, make the work more safe, efficient and precise than ever before.
