The testo 550 digital manifold can now make working on refrigeration systems and heat pumps even easier: the instrument can be used for 60 refrigerants, calculates superheating/subcooling automatically and can now also be connected to a practical smartphone/tablet app. The app makes the operation and the documentation of measurement results significantly more convenient. 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.
