Digital manifolds and the testo Smart Probes AC & refrigeration test kit outperform analog measuring technology in many respects.

More precise results

• At least twice as accurate: The testo 550 2-way manifold and the testo 570 4-way manifold have an accuracy of ± 0.5% of f.v. (± 0.3 bar) for a measuring range of 60 bar.
• Unambiguous values: You can always rely on the measuring values displayed and the long-term stability of the measuring technology.

Automatic refrigerant updates

• Simply switch on and measure: Up to 60 common refrigerants are already stored ex works in a digital manifold.
• New refrigerants? No problem:  Refrigerant updates are quickly carried out using the App and software.

Intuitive measurement menus

• Automatic calculation: Evaporation and condensation temperature, along with superheating and subcooling. No more error-prone manual calculations.
• Optimized operation: User-oriented measurement menus guide you through the measurement efficiently and conveniently.

In addition to the automatic calculation of evaporation and condensation temperature, along with superheating and subcooling, a Testo digital manifold supports you in these applications:

• Controlling vaporiser superheating
• Controlling suction steam superheating
• Checking the effect of internal liquid/suction steam heat exchangers (IWT)
• Checking the driving temperature difference

 When you measure with a Testo Digital manifold:

• you have all refrigeration and air conditioning systems under control.
• you improve the efficiency and ecological balance sheet of your systems.
• you increase your customers' satisfaction.
• you avoid unnecessary servicing work.
• you work in an efficient and forward-looking way using digital measuring technology.
