testo 557 - digital manifold kit
Extensive accessories included: set of 4 filling tubes, 2 x clamp temperature probes, precise external Pirani gauge for vacuum measurement and transport case
Calculation of superheating and subcooling in real time for 60 refrigerants: no error-prone manual calculation
Connection to smartphone/tablet App: remote monitoring, clever measurement documentation and refrigerant updates
Temperature-compensated leakage test, automatic ambient pressure measurement
The testo 550 digital manifold is your perfect companion for working on refrigeration systems and heat pumps and can be used for 60 refrigerants, calculates superheating/subcooling automatically and can easily be connected to a practical smartphone/tablet app.
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.
60 refrigerants stored in the instrument: one instrument covers all the most important refrigerants and different manifolds are not required for each refrigerant. (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!
Advantages of Installing App:
Remote monitoring of the measurement: 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: 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: 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: 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
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.
Digital manifold: sturdy, simple and practical
Not only is the robust 2-way valve block, which is made of metal with 3 connections and 3 hose holders, created for harsh working environments, it is also easy to use. The sturdy housing reliably protects the testo 550 digital manifold against impacts (protection class IP 42). The suspension hook secures the instrument during the measurement. The large, illuminated display enables quick, easy read-off, even when visibility is poor.
