Wöhler FA 320
2. Specifications
2.1 Application
The Wöhler FA 320 Fan Anemometer is a handy, handheld instrument designed
to measure the flow velocity, temperature and relative humidity of air. It can be
used for example for the measuring of ventilation plants, in housing spaces etc.
Because of the integrated average determination of eight measuring points it will
be possible to measure even large outlets. In this case the air volume flow will be
calculated automatically.
The user can select between different units (°C, °F, %rH, m/s, ft/m, m³/m, cfm,
cm, inch).
