testo 550 review

The Testo 550 Digital Manifold can now make work on refrigeration systems and heat pumps even easier: the unit can be used for 60 refrigerants, automatically calculating superheat/ sub-cooling, and can now also be connected to a practical app for smartphones/tablets. This application makes the use and documentation of measurement results much more convenient.

Do you work on refrigeration systems and heat pumps on a daily basis? If so, the testo 550 gauges 2-way manifold is your perfect companion. testo gauges 550 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 are 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. to buy testo 550 digital manifold or wanted to know about testo 550 digital manifold price visit our website.
