Finding leaks
Leaks in a refrigeration system, such as an air conditioning system, can quickly have serious consequences. The system would no longer provide the required cooling capacity and, in the worst case scenario, the refrigeration system may even be damaged. The leak detectors from Testo can detect even the smallest leaks.

The Testo tools in use
With the testo 558s, the system density can be assessed easily and reliably, thanks to the clear visualization of pressure values and temperature compensation.
Thanks to the large colour display and wireless connection to the probes, all important parameters are visible at a glance. The 30-minute trend curves also ensure even more reliable analysis.
Make your work easy – with the testo 565i.
Fully automatic evacuations with auto-stop function and self-starting vacuum hold test.
