Testing refrigeration systems

Determination of subcooling and superheating on refrigeration systems or heat pumps faster is simply faster. The testo Smart Probes refrigeration set means you can test all parameters accurately.

  • Low refrigerant loss thanks to hoseless installation directly onto the pressure connection
  • Direct display of the evaporation and condensation temperatures
  • Analysis and transmission of measurement data via Smart Probes App

Refrigeration gauges

In the digital age, there's no reason to struggle with analogue technology. At Testo, we developed three digital refrigeration gauges for the modern technician.

  • Now with 60 refrigerant profiles and the added functionality of leak tests
  • Testo digital manifolds are versatile enough to be the tool for every job

Vacuum gauges

The testo 552 Vacuum Gauge offers fast and accurate readings as to how effectively heat pumps and refrigeration systems are dehumidifying and removing foreign matter.
