Key Benefits:

Automatic superheating/subcooling calculation: eliminates manual errors
Smartphone/tablet app: remote display, graphical progress tracking, and data documentation
Temperature-compensated leak test: improves accuracy in detection
Supports 60 refrigerants (updateable via app)

 

Product Description:

If you work daily on refrigeration systems or heat pumps, the Testo 550 2-way manifold is an essential tool. It combines multiple functions into one device, reducing the need for multiple instruments:

Quick and accurate pressure measurements using two temperature-compensated sensors; automatic identification of evaporating and condensing temperatures.
Two temperature inputs for attachable probes, enabling simultaneous superheating and subcooling calculations—eliminating manual errors.
Includes two clamp temperature probes for reliable surface temperature readings.
No need to switch refrigerant hoses due to the automatic heat pump mode.
Stores 60 refrigerants, covering most common ones (refrigerant updates available via app).
Other features include temperature difference display and temperature-compensated leak testing.
Connect your device to the Testo 550 app for enhanced functionality.

Download the free Testo 550 app on your smartphone or tablet to enjoy features like:
Remote monitoring of measurements from up to 20 meters away.
Real-time numerical and graphical display of data on your device.
Document measurements in PDF or CSV format, and share them via email.
Update refrigerant profiles directly through the app for improved performance and adaptability.


Durable, Simple, and Practical Design:

The robust 2-way valve block, made of metal with three connections and hose holders, is built for tough environments. The durable housing protects the device against impacts (IP 42 rating). A suspension hook keeps the unit secure during use, and the large illuminated display ensures easy reading even in low light.


What's Included:

Testo 550 digital 2-way manifold, two clamp temperature probes, transport case, calibration certificate, batteries, and the downloadable app.
