Testo 550i – Smart Kit

The Testo 550i Smart Kit is a digital 2-way manifold designed for technicians looking for a compact, lightweight instrument that can be fully controlled via an app.

Thanks to Bluetooth connectivity, all functions – from refrigerant selection to measurement recording – are managed directly from a smartphone or tablet, offering maximum convenience and reducing intervention times.

The rugged construction and compact design allow for operation even in very tight spaces. The ability to connect wireless probes for temperature, vacuum, and other parameters makes the 550i an extremely versatile device, suitable for refrigeration, air conditioning, and heat pump systems.
