- Unambiguous values: You can always rely on the measuring values displayed and the long-term stability of the measuring technology.
Automatic refrigerant updates
- Simply switch on and measure: Up to 60 common refrigerants are already stored ex works in a digital manifold.
- New refrigerants? No problem: Refrigerant updates are quickly carried out using the App and software.
Intuitive measurement menus
- Automatic calculation: Evaporation and condensation temperature, along with superheating and subcooling. No more error-prone manual calculations.
- Optimized operation: User-oriented measurement menus guide you through the measurement efficiently and conveniently.
