The advent of digital technology means huge quality improvements when it comes to the adjustment of refrigeration systems or heat pumps.
Digital manifolds provide high-precision temperature and pressure measurements, determine subcooling and superheating, but also enable reliable evacuation of the system through accurate vacuum measurement.
And the convenient testo refrigeration App makes commissioning, maintenance or repair even quicker!
One measuring instrument – all parameters
Commissioning, maintenance and/or repair? No matter where the focus of your work on refrigeration systems and heat pumps is, Testo has the appropriate digital manifold for you.
The digital manifolds testo 550s and testo 557s including Bluetooth and 2- or 4-way valve block feature
High-quality measurement technology, high level of reliability and clever functions for fast and easy measurement and documentation.
The App-controlled digital manifold testo 550i
offers great measurement technology in especially compact format.
With the extremely robust manifold, you deal with your daily jobs on refrigeration systems wirelessly, easily and reliably. All with the testo Smart App on your smartphone or tablet.
Here you can see which digital manifold is the right one for your requirements:
