The testo 549 digital manifold offers many advantages in comparison with analog manifolds: the instrument will make it easier for you to work on refrigeration systems and heat pumps. With its integrated temperature measurement and automatic calculation of superheating/subcooling, you can now do away with additional measurements and manual comparisons (when using an optional clamp probe). You can also use the manifold for 60 current refrigerants.
60 current refrigerants stored in the instrument
Calculation of superheating and subcooling in real time (with optional clamp probe): saves you from having to carry
Temperature-compensated leakage test
Two temperature-compensated pressure sensors
Features
You can also view the temperature difference via the 2-way manifold. The automatic heat pump mode, which makes switching over the refrigerant hoses unnecessary, is also really practical.
