Mold Assessment Technician Practice Exam

What type of meter would typically provide subjective readings for moisture levels?

1. Digital moisture meter

2. Capacitive moisture meter

3. Subjective meter

4. Conductive moisture meter

The correct answer is: Subjective meter

A subjective meter is designed to provide qualitative rather than quantitative readings of moisture levels. This type of meter typically relies on visual indicators or other non-numeric means to convey information about moisture presence, which can vary based on the operator’s interpretation. Such instruments are often used for preliminary assessments where specific moisture levels are not critical and where the operator can assess the environment based on experience and observation. In contrast, digital moisture meters, capacitive moisture meters, and conductive moisture meters are calibrated to provide specific numerical values for moisture content, thus allowing for more precise measurements. Digital moisture meters often display moisture levels as percentages, offering clear data. Capacitive meters use a non-invasive method to detect moisture by measuring changes in capacitance, while conductive meters measure the electrical resistance of materials to determine moisture content.
