Testo 557 digital manifold kit - with Bluetooth and set of 4 hoses

DISCONTINUED
Product code: IC-0563-2557

Unfortunately, the testo 557 has been discontinued and has been replaced by the testo 557s Smart Vacuum Kit with four filling hoses

The testo 557 digital manifold fulfils numerous functions, which are required for working on refrigeration systems and heat pumps, in just one instrument: for example 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.

Overview

Are you primarily entrusted with the commissioning or maintenance of refrigeration systems or heat pumps? If so, the testo 557 is the ideal digital manifold for you: like the testo 550, this digital manifold replaces multiple tools in the refrigeration industry and can be connected to a practical app. As well as the features of the testo 550 manifold, the testo 557 offers a high-precision external Pirani gauge for vacuum measurement: this enables the quick, safe evacuation of refrigeration systems and heat pumps.
State-of-the-art technology, to make your work easier: the digital manifold in detail
The testo 557 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. See all the advantages at a glance: testo 557 digital 4-way manifold including two clamp temperature probes, precise external Pirani gauge for vacuum measurement, transport case, calibration protocol, batteries and app (can be downloaded) - Non sight glass!
