The Testo 550i is a two-way valve block with Bluetooth designed for commissioning, servicing, and maintaining refrigeration systems and heat pumps.Please see the ‘What’s Included?’ section for more information.

Here's a quick introduction to Testo's range of manifolds:

Bluetooth connectivity and the Testo Smart App allow technicians to control servicing and maintenance work, from measuring to documenting, via their smartphone or tablet. When the Testo 550i is used with the Testo Smart App, technicians can view and document measurements. The Testo Smart App also automatically calculates refrigerant-specific evaporation and condensation temperatures and provides convenient refrigeration management: users can set favourites and are provided with automatic updates. 

Additionally, via Bluetooth and the Testo Smart app, the Testo 550i Digital Manifold can be wirelessly connected to Testo’s smart temperature, pressure, and humidity probes, offering greater flexibility.

The Testo 550i is a small, simple-to-use manifold with a robust hook and durable IP54 housing. It delivers fast and easy measurements as well as consistently high performance in all conditions. When used with the Testo Smart App, it is particularly well suited to applications involving AL2 refrigerants and all relevant legislation, norms, and guidelines for these refrigeration systems.
