0563.2557/TE

Perfect for maintenance of a heat pump or for installation of an air conditioner, the TESTO 557 includes the advantages of the TESTO 550 measurement instrument with an external Pirani probe useful for making measurements when creating a vacuum on a refrigeration installation.


Two pressure sensors with temperature compensation can be used to measure the HP and the LP quickly, depending on theoretical evaporation and condensation temperatures. You can use 2 clamp-on temperature probes to accurately measure the surface temperature .


The TESTO 557 measurement instrument is used on 60 coolants, pre-recorded in the instrument and that can be updated using the free application.
