testo 550s Smart Kit digital manifold with temperature probes and 3 hoses

• Determination of high and low pressure, automatic determination of condensation and evaporation temperature and calculation of superheating/subcooling. All results can be read simultaneously on one screen
• Tightness test: Recording and analysis of the pressure curve
• Automatic calculation of the target superheat (in conjunction with the appropriate measuring instrument, e.g. Testo Smart Probe)
• Measure vacuum: Graphic progression display of the measurement with indication of the start and differential value
• Evacuation: Graphic progression display of the measurement with indication of the start and differential value (in conjunction with the appropriate Testo Smart Probe, e.g. testo 552i vacuum probe).

The testo 550s digital manifold with Bluetooth and a 2-way valve block features a large graphic display, a compact, robust housing, guided measurement menus and the testo Smart App. Top-quality measurement technology, a high degree of reliability and smart functions for quick, easy measurements and documentation make the testo 550s manifold a reliable partner for your commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps.
