TESTO Brand Refrigeration Digital Manifold Gauge Set Testo 550

Specification:

The testo 550 digital manifold is designed to simplify work on refrigeration systems and heat pumps. With support for 60 different refrigerants, it automatically calculates superheating and subcooling, and now offers a convenient smartphone or tablet app connection. This app makes operation and data documentation much more efficient.

 

Product Benefits:

Automatic calculation of superheating/subcooling – no more manual errors
App integration for remote display, graphical progress tracking, and measurement documentation
Temperature-compensated leak testing
Supports 60 refrigerants (updateable via app)

 

Product Description:

If you're working with refrigeration systems and heat pumps daily, the testo 550 2-way manifold is your ideal tool. It combines multiple functions into one device, eliminating the need for several other instruments:

Fast and accurate pressure measurements using two temperature-compensated sensors; automatic detection of evaporating and condensing temperatures
Two temperature inputs for attached probes that allow simultaneous calculation of superheating and subcooling, reducing error-prone manual calculations
Two clamp temperature probes included in the package for reliable surface temperature readings
No need to switch refrigerant hoses thanks to the automatic heat pump mode
60 refrigerants are built-in (with updates available via the app)
Additional features include temperature difference display and temperature-compensated leak testing.
Connect your smartphone or tablet to the app for enhanced functionality!

Download the free testo 550 app onto your smartphone or tablet to access features like:
Remote monitoring of measurements from up to 20 meters away
Real-time numerical and graphical display of data on your device
Easy documentation of results in PDF or CSV format, with email sharing options
Photo integration for reports
Refrigerant updates to keep your device current with new refrigerants

 


Digital Manifold: Durable, Simple, and Practical

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 instrument secure during use, while the large, backlit display ensures easy reading even in low light conditions.


Scope of Delivery:

Testo 550 digital 2-way manifold, including two clamp temperature probes, transport case, calibration certificate, batteries, and app (available for download).
