Do you work on refrigeration systems and heat pumps on a daily basis? If so, the testo 550 2-way manifold is your perfect companion. It offers you so many functions in just one instrument that you will be able to do away with several of your other instruments:
-
Quick, accurate measurement of high and low pressure with two temperature-compensated pressure sensors; automatic detection of evaporating and condensing temperature
-
Two temperature inputs for attachable temperature probes for the simultaneous calculation of superheating and subcooling: you can therefore do away with manual calculations, which are prone to error, and get a reliable result straight away
-
Two clamp temperature probes included in the delivery: when clamped directly onto the cables, these enable reliable measurement of the surface temperature
-
No need to switch over refrigerant hoses: thanks to automatic heat pump mode
-
60 refrigerants stored in the instrument: just one instrument covers all the most important refrigerants and, depending on the refrigerant, you don't need different manifolds (refrigerant update possible via app)
Moreover, the 2-way manifold offers other functions and features such as the display of temperature difference or the temperature-compensated leakage test.
Right app for the instrument: connect the manifold to your smartphone/tablet!
