Testo 550i | Manifold

Contact Instrument Solutions

The Testo 550i digital manifold enables service engineers to control their daily servicing work on refrigeration and air conditioning systems entirely from their smart phone or tablet. Fitted with a 2-way valve block and robust hook, the Testo 550i saves you time with its fast and easy measurements, clearly presented results and digital documentation.

The Testo 550i comes as a manifold only or as a kit with two Testo 115i wireless smart temperature clamp probes in a robust had case.

Wireless Bluetooth connectivity and easy to use Testo Smart Probes App make it considerably easier to work on measuring points that are a long distance apart. All measurement data are presented either as a diagram or a table and data reports can be emailed directly as a pdf or Excel file. The handy testo Smart Case (Smart kit version only) enables the measuring instruments to be conveniently transported and ensures that they are always to hand when they are needed.
