testo releases next generation of digital refrigeration manifolds

testo introduces its next generation of digital refrigeration manifolds
featuring 60 refrigerant profiles and a new leak testing functionality.

Designed and priced to make analogue obsolete, the new digital
refrigeration manifold range includes the testo 549, testo 550, and testo 557
models. An optional Bluetooth capability will also allow users to connect to testo’s
brand new Refrigeration App, which is exclusively available to testo customers.

Brand new App and Bluetooth

The App integration via Bluetooth for testo 550 and testo 557 expands
the user’s ability to work faster and more efficiently. The App enables the
user to read measurement data directly on a smartphone or tablet, allowing them
to finalise and send measurement reports directly from the site. The list of
stored refrigerants can also be easily updated via the App.

testo’s digital manifolds make many of the typical refrigeration
contracting tools obsolete. The user can also select the most important
refrigerants for even faster access.

Better performance

Though analogue manifolds are still widely used in the refrigeration
industry, digital manifolds are the future of refrigeration engineering. The
new testo manifolds deliver enhanced performance with the pressure ranges of
the 549, 550 and 557 variants increased to 60 bar; battery life extended to 250
hours; and choice of 60 common refrigerants stored in the instrument. The
robust design features a new metal frame around the display.

One instrument to cover every

testo’s digital refrigeration manifolds are designed to meet all the day-to-day
challenges in refrigeration contracting, enabling the user to measure various
operating parameters with a single instrument. The digital manifold helps the
contractor get a comprehensive overview of the condition of a refrigeration
system or heat pump in real time.

testo’s new digital manifolds combine the price advantage associated
with analogue measurement with the undeniable precision of digital measurement.

testo 549: The best value

Offering the best price-performance value among all the models, the testo
549 digital manifold precisely measures high side/ low side pressure and
instantly displays the corresponding saturation/ evaporation temperatures for
60 refrigerants. Optional temperature probes enable automatic superheat and
sub-cooling calculations to be displayed.

testo 550: Bluetooth
capabilities and new Refrigeration App

Offering instant display of superheat and sub-cooling for up to 60
refrigerants, testo 550 also measures high side/ low side pressures and
temperatures. The Bluetooth connection opens up new possibilities for efficient
analysis and documentation.

testo 557: Precision measurement
(coming soon)

Offering all the strong points of testo 550, the testo 557 digital
manifold will feature a 4-way valve block for fast, safe and efficient work in
commissioning, service and maintenance. A new highly precise external probe delivers
even more reliable performance.
