Refrigeration Manifolds


Testo is setting standards in refrigeration technology with the digital manifolds range for measuring, recording, regulating, analysing, serving and commissioning air conditioning, system refrigeration plants, and heat pumps.

With testo digital manifolds much of the traditional refrigeration equipment becomes obsolete. And now with testo's new smart equipment range, you are able to transport all measurement data directly to your Smart Phone or tablet via Bluetooth connection. Testo refrigeration instruments are also now more affordable than ever, so there has never been a better time to make the switch to digital. 

The Smart world of Refrigeration

 With testo's new Smart technology HVAC measurements are be more effecient than ever


Brand New App and Bluetooth capabilities

The App integration via Bluetooth for the testo 550 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.

 Testo manifolds' new Bluetooth capabilities make it easier than ever to manage your jobs

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 549, 550 & 557 have all been increased to 60 bar, the battery life extended to 250 hours, and there are 60 common refrigerants stored in the instruments. 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.

1 instrument to cover every job

According to numerous studies conducted by government organisation “Energy Star”, up to 74% of all refrigeration systems are incorrectly configured using analogue measuring technology.* Analogue gauges been proved inaccurate, inconvenient to handle, and they require the user to interpret the measurement results.


No matter how tough the job is, our New refrigeration manifolds are be up to the task

With digital manifolds from Testo, you are equipped for all day-to-day challenges in refrigeration contracting. You can measure various operating parameters with only one instrument. Get a comprehensive overview of the condition of a refrigeration system or heat pump in real time, whenever you need it.

Such reliable measurement results lead to efficiently-configured refrigeration systems, and have even been proven to save up to 12.5% of energy costs* – plus you need considerably less work time.


Measurement Solutions for Refrigeration Technology

By using digital manifolds from Testo, one instrument records a wide range of parameters: they can measure pressure and temperature values quickly and easily, or carry out temperature compensated tightness testing. Data can be stored and evaluated via the App and measurement protocol can be printed out directly on site.

Testo's new Digital manifolds incorporate both the price advantage formerly associated with analogue measurement, and the undeniable precision that only digital equipment can offer.
