✔ Automatic superheating/subcooling calculation: no more need for manual calculations, which are prone to error ✔ With practical testo Smart App: Remote display and operation, graphic curve display, measurement value storage and documentation ✔ Temperature-compensated leakage test ✔ 60 current refrigerants are included in the manifold (update possible via app) 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. Product Description 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
