Product Description
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.
Â
(1) Automatic superheating/subcooling calculation: no more need for manual calculations, which are prone to error
(2)With a practical app: (remote) display, graphical progress display, documentation of readings
3)Temperature-compensated leakage test
(4)60 current refrigerants are included in the manifold (update possible via app)
Features
Right app for the instrument: connect the manifold to your smartphone/tablet!
Install the free app for the testo 550 digital manifold on your smartphone/tablet and take advantage of a host of practical features:
- Remote monitoring of the measurement:Â you can track the measurement from your smartphone/tablet, so there's no need for you to stay right next to the manifold; coverage of up to 20 m where there are no obstructions (at the very least)
- Measurement data display on your smartphone/tablet:Â you can follow the measurement in numerical form and as a graphical progress display on your smartphone/tablet - really practical if you are configuring the system at the same time
- Useful documentation functions:Â use the app to store measurement results (in pdf or csv format) and also send them directly via e-mail. If you have taken a photo of the measuring location using your smartphone/tablet, you can also insert this into the documentation
- Refrigerant update:Â use the app to carry out refrigerant updates in order to ensure that your digital manifold is kept up to date at all times regarding its refrigerants, or to adapt the list of refrigerants to suit your requirements
Â
The app is available for both Android and iOS. Once the app is installed, a connection between the manifold and your smartphone/tablet can be established via Bluetooth.
