What else I would like to say to other installers, the device really saves a lot of time, you don't have to take as much stuff with you, and the testo 557s does everything for you.

In the past, we had to work with analog measuring devices, 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, a feature packed, measuring set, the purchase of which you certainly won't regret as a cooling technician. I don't think any other brand can compete.
