Testo 550s Smart Digital Manifold

Description

The Testo 550s is a compact, ergonomic, and robust (IP54) instrument designed for commissioning, servicing and maintaining refrigeration systems and heat pumps. It includes a two-way valve block enabling faster measurements on refrigeration systems, air conditioning units, and heat pumps, and Bluetooth for connecting with the Testo Smart App as well as Testo Smart Probes. Please see the video below for a brief introduction to Testo’s range of digital manifolds.

The new generation of digital manifolds: testo 557s, testo 550s and testo 550i

The Testo 550s is available as part of three sets: Basic, Smart, and Smart with Hoses. Please see the ‘What’s Included?’ section for more details.

Technicians can view and evaluate measurements on the large, graphic display. The Testo 550s Smart Digital Manifold also includes measurement menus designed to guide users through the measurement processes for superheat, pressure drop test, and vacuum.

Bluetooth connectivity enables wireless connection to Testo’s Smart App which in turn facilitates a connection to Testo’s Smart Probes enabling the measurement of temperature, humidity, and pressure. Additionally, the Testo Smart App can be used to view measurements remotely and create digital documentation on-site. It also offers convenient refrigeration management: technicians are sent automatic updates and may set favourites which can be transferred to the Testo 550s Smart Digital Manifold for faster, easier measurement.

The Testo 550s is particularly well suited to applications involving A2L refrigerant and corresponding legislation, norms and guidelines relating to these refrigeration systems. It is a durable, dependable, and adaptable digital manifold capable of consistently delivering high performance in all conditions.
