Air flow meters
Here you will find efficient and reliable handheld instruments and products used to measure airflow in all kinds of spaces. For example, airflow can be measured with an anemometer (vane anemometer or hot wire anemometer) or an airflow sensor. Measurements can be made in ducts, on pipes or over filters.
