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 refrigeration technician. I don't think any other brand can compete.

More moisture meters from Testo
A pressure gauge ensures that water and gas pipes, along with gas heating systems, function properly. An absolute pressure meter is particularly suitable for flow measurement in ducts, laboratories and production processes, because it compensates the density.
On the one hand, a leak detector is indispensable for detecting escaping refrigerant and on the other hand for discovering leaks on gas pipes. At the same time, alarms and flexible probes ensure a whole lot more safety and convenience.
Do you want to evacuate refrigeration systems in accordance with the manufacturer's specifications regarding absolute pressure? Then you should take a look at our testo 552 vacuum gauge. Its high-precision, flexible alarm threshold values and App connection provide everything you could possibly wish for.
