App and Bluetooth Work more conveniently and efficiently.

testo 549, testo 550, testo 557, testo 570 Measure digitally, work efficiently. Test refrigeration systems quickly and safely using digital manifolds. These days, many spheres of life would be unthinkable without digital technology. The refrigeration industry is no exception. Yet analog manifolds are still widely in use in refrigeration technology. According to numerous studies, among others conducted by the US government organisation “Energy Star”, up to 74% of all refrigeration systems are incorrectly configured using analog measuring technology.* It is inaccurate, inconvenient to handle, and...

Including efficiency App: testo 550 and testo 557. With App and Bluetooth, you simply measure more conveniently and efficiently. With their App integration via Bluetooth, testo 550 and With the digital manifold testo 557, many of the refrigeration testo 557 open up new possibilities for efficient analysis contractor's tools become obsolete, and are replaced by and documentation. The App allows you to comfortably only one – and a very precise one at that. In comparison to read out the measurement data on your Smartphone or the new testo 550, this digital manifold offers a 4-way valve tablet. In...

Find any leak easily. testo 316-3 and testo 316-4: the leak detectors for all common refrigerants. Leakages in a refrigerant system have serious For more demanding applications, we recommend the consequences. The system no longer provides the testo 316-4. This leak detector also features high sensitivity required cooling capacity and, in the worst case scenario, (3 g/a) and a trend display function as well, enabling you to system components can be damaged. Not to mention the detect maximum system leakages. The permanent sensor environmental damage and the costs incurred by your check ensures...
