What role does an anemometer play in appliance testing?

An anemometer is an instrument specifically designed to measure the speed and direction of airflow. In the context of appliance testing, its primary role is to assess ventilation effectiveness. Proper airflow is critical for combustion appliances to function effectively and safely. Adequate ventilation ensures that there is a sufficient supply of oxygen for the combustion process and that exhaust gases are effectively vented out, which is crucial for preventing dangerous conditions such as carbon monoxide buildup.

By measuring airflow, an anemometer helps testers determine if an appliance is receiving enough air for combustion and whether the ventilation system is functioning as intended. This information is vital for ensuring that combustion appliances operate safely and efficiently, ultimately protecting both the appliance's performance and the safety of individuals in the vicinity.
