Mold Assessment Technician Practice Exam

Which piece of equipment is commonly used by mold assessors to measure air quality?

1. Thermometer

2. Humidity gauge

3. Particle counter

4. Moisture meter

The correct answer is: Particle counter

Mold assessors commonly use a particle counter to measure air quality because it directly determines the concentration of airborne particles, including mold spores. This piece of equipment provides quantitative data about the presence of mold in the air, which is crucial for assessing potential health risks, identifying contamination, and determining the effectiveness of remediation efforts. While other tools like a thermometer can measure temperature, a humidity gauge can ascertain moisture levels in the air, and a moisture meter can detect moisture content within materials, none of these directly quantify the presence of airborne mold spores. The particle counter focuses specifically on air quality dynamics, thereby making it essential for mold assessment.
