The professional and reliable execution of an evacuation is an indispensable work step before the initial commissioning or recommissioning of a refrigeration system. This ensures that there is no moisture, foreign gases, oil and refrigerant residues in the refrigeration system before charging.

In the past, we had to work with analog meters, a notepad, and external temperature sensors. Testo has now incorporated all of this into a single device. This makes it much easier and much quicker for us to satisfy the customer with the performance of their device.

My first impression is very positive; the testo 557s is a very nice, Smart Digital Manifold, a purchase which you won't regret as a cooling technician. I don't think any other brand can compete.
