What is the primary purpose of a velometer?

1. To measure light intensity

2. To analyze chemical composition

3. To measure air velocity

4. To assess sound levels

The correct answer is: To measure air velocity

The primary purpose of a velometer is to measure air velocity. This instrument is specifically designed to quantify the speed at which air moves within a given environment. Accurate measurements of air velocity are crucial in various applications, particularly in industrial settings, HVAC (heating, ventilation, and air conditioning) systems, and safety assessments, where air movement impacts ventilation efficiency and respiratory safety. Using a velometer helps ensure that working environments maintain proper airflow, thereby supporting effective dust control, gas dilution, and worker comfort. Understanding air velocity can also assist in ensuring compliance with safety regulations and improving overall environmental conditions within workplaces. In contrast, the other options reference different measuring tools that assess unrelated parameters, such as light intensity, chemical composition, and sound levels. Each of these functions is served by specialized equipment tailored for those specific types of measurements, whereas the velometer is distinctly focused on air movement.
