Handy, robust, smart: Introducing the new digital manifolds from Testo, the world market leader for measurement technology. These smart tools are designed to assist the contractors and technicians in the field of air conditioning and refrigeration. The new instruments are suited to all user groups and measurement types, whether traditionally analog or digitally modern, and meet all measurement challenges. The new digital manifolds allow fast measurement and easy operation via large graphic display and a smartphone – and yet are maximally compact and rugged. They are fully digitally, extremely robust with protection class IP 54, and have many functions, which make day-to-day work on refrigeration systems and heat pumps even easier. The new digital manifolds come in practical kits – so users are optimally equipped for all measurement tasks.

testo 550s and testo 557s: Smart digital manifolds with Bluetooth and 2-way or 4-way valve block

The testo 550s and testo 557s digital manifolds make working on air conditioning and refrigeration systems easier than ever before. A large graphic display guarantees a clearer display of all measurement data and the evaluation of the results, which can then be wirelessly transferred to the testo Smart App. Guided measurement menus accompany the measurement and allow the automatic recording of important parameters. Bluetooth probes can be wirelessly and automatically connected to the instrument with a range of up to 150 m, making work with the testo 550s and testo 557s even more convenient.

testo 550i: App-controlled digital manifold with Bluetooth and 2-way valve block

The testo 550i is the smallest fully digital manifold in the market, which can be completely controlled by a smartphone or tablet. At the same time, it guarantees maximum reliability thanks to its robust housing with IP54 protection class. It communicates wirelessly and automatically via Bluetooth 5.0 with the wireless testo Smart Probes for temperature, pressure and humidity, and calculates parameters automatically in the testo Smart App: The testo 550i thus saves considerable time in daily servicing and maintenance work.

testo 552i – App-controlled wireless vacuum probe

The new vacuum probe testo 552i makes things easy for users as the vacuum is measured wirelessly without the need of hose and via just one service port – ensuring no loss of refrigerant. The measurement values are shown in the display of the digital manifold or in the testo Smart App. The probe communicates via Bluetooth with the testo Smart App, which supports with numerous intelligent functions (e.g. graphic presentation of the vacuum). A robust, ergonomic housing and proven German measurement technology make the vacuum probe a compact and reliable companion.

testo Smart App – all data at glance

One for all: The testo Smart App is the optimum complement to the new digital manifolds and other Bluetooth-capable measuring instruments from Testo. Carrying out measurement and documentation is easy and mobile via App. Intuitive menus guide the user step by step through the configuration and implementation of the measurement. Measurement data are displayed in an illustrative and graphic way, allowing the results to be evaluated quickly. With just one click, reports arrive.
