With heating measurement solutions from Testo, you are ideally equipped for all measurement tasks in your everyday work on all heating systems - and thus do your job even more professionally, reliably and quickly!
In order for heat pumps to reliably provide sustainable heat, and for the heating curve to be right, they have to be thoroughly checked using suitable measurement technology at regular service and maintenance intervals.
An annual service is also recommended for all heat pumps with refrigerant. This is way, efficient operation is ensured, and your customers can save costs.
With a digital manifold, you can carry out the commissioning and service of heat pumps quickly, flexibly, and precisely. Bluetooth, wireless probes and the testo Smart App make measurement and documentation easier.
Perform high-precision measurements in no time
Ensure tightness of refrigeration systems
Test and optimize the efficiency of the system
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.
