Hidden malfunctions can often only be found through long-term measurements, e.g. in the case of irregularities in pressure, temperature or the electrical system. Thanks to the intelligent error analysis of the testo 570s, anomalies are immediately pointed out without having to search for a long time.
The testo Smart App guides you quickly and easily through measurements on refrigeration, air conditioning and heating systems.

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, you don't have to do as much yourself, because the testo 557s does everything for you.

In the past, we had to work with analogue measuring devices and needed a notepad and we needed 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 very nice, new measuring set, the purchase of which you certainly won't regret as a cooling technician. I don't think any other brand can compete.
