What tool can a mold assessor use to evaluate potential mold growth in a building?

Temperature gauge
Humidity meter
Thermal imaging camera
pH meter

The correct answer is: Humidity meter

A humidity meter is an essential tool for a mold assessor because mold thrives in environments with high moisture levels. By measuring the humidity in a building, an assessor can identify areas that have conditions conducive to mold growth. Generally, indoor humidity levels above 60% can promote mold development, making the humidity meter a critical device for assessing the likelihood of mold presence. While other tools like a thermal imaging camera can be useful for identifying moisture patterns or hidden water leaks, and a temperature gauge helps assess the overall environment, the humidity meter directly relates to mold growth factors. A pH meter is more suitable for assessing acidity or alkalinity in substances, which does not directly correlate with evaluating mold potential in a building setting. Recognizing the importance of monitoring relative humidity levels helps mold assessors effectively determine areas at risk, ensuring a comprehensive evaluation.
