Efficient adjustment of air conditioning systems and heat pumps
The hallmark of a great tool is that it makes a technician's job easier. Testo's refrigeration technology including the testo 550i, testo 550s & 557s refrigeration gauges fit this criteria.
There are two main components of a heating, ventilation and air-conditioning specialist's job - testing and servicing. With the right tools in hand, the work day is made a breeze.
Testo refrigeration manifolds (testo 550s, 557s, 550i) come with smartphone connectivity with the ability to send and receive results in real time.
For quick hose-free installation the testo Smart refrigeration set allows technicians to test systems more accurately without any refrigerant loss. See the various testo Smart Probes kits via the links below.
