The advent of digital technology means huge quality improvements when it comes to the adjustment of AC/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 AC/refrigeration App makes commissioning, maintenance or repair even quicker!
