Rotating Vane Anemometer 6820 Series
Industrial-grade 2.75-inch vane series with automatic volume-flow calculation and models for velocity only, velocity/temperature or velocity/temperature/humidity.
Products
| Product | Product line | Application area | Selection note |
|---|---|---|---|
| 6820 Series | Rotating-vane anemometers | Velocity and calculated volume flow with model-dependent T/RH | Diffusers, grilles, ducts and industrial ventilation |
Key Features
Three model configurations
Choose velocity/volume only, velocity plus temperature, or velocity plus temperature and humidity.
Automatic volume-flow calculation
Enter duct dimensions to calculate CFM or CMH directly.
Ten stored duct sizes
Frequently used dimensions remain available after power-off.
Industrial field package
The 2.75-inch vane probe and robust enclosure support HVAC and industrial ventilation work.
