New Testo 550

New Testo 550: Just switch on, measure, and read off Large figures allow the values to be read off the display quickly and easily. Two temperature-compensated pressure sensors measure high and low pressure quickly and precisely, and automatically calculate the temperatures. A glance at the instrument display is enough, and you see the measurement result.

Two temperature inputs guarantee you the simultaneous calculation and display of superheating and subcooling. The temperature can additionally also be displayed. By simply pressing a button, you can switch between the measurement tasks at your will.

With the option of Bluetooth capability users can now connect to our Brand New Testo Refrigeration App, which is exclusively available to Testo customers.


Testo's new manifold range are incredible value, completely negating the price advantage of analogue gauges

Brand New Refrigeration App and Bluetooth capabilities

The App integration via Bluetooth for the testo 550 and the testo 557 is perhaps the biggest strength of the new manifolds. It gives users new possibilities for working faster, more comfortably, and therefore more efficiently.

Using the App measurement data can be read directly on a Smartphone or tablet, and measurement reports can be finalised and sent directly on site. The list of stored refrigerants can also be easily updated via the App.

With Testo digital manifolds, many of the refrigeration contractor's tools become obsolete, and are replaced by only one – and a very precise one at that. There is also an option to select your most important refrigerants as favourites, for even faster access.

A new, better-performance generation

Another major strength of the New Testo manifold range is their increased performance capabilities. The pressure ranges of the 550 has been increased to 60 bar, the battery life extended to 250 hours, and there are 60 common refrigerants stored in the instrument. A new metal frame around the display has also been installed, making the instruments more robust than ever.

These days, many spheres of life would be unthinkable without digital technology. Most of us wouldn’t be without our Android or IPhone, and the days of the Nokia 3310 for example seem a distant memory. The refrigeration industry is no exception to this logic, yet analogue manifolds are still widely used.

 Admittedly many refrigeration engineers started with analogue gauges and therefore don’t know anything different, but isn’t it time for an upgrade? We all grew accustomed to our 3310 but at some stage we had to accept it became outdated. Digital manifolds are the future of refrigeration engineering.
