Moisture is measured for a variety of reasons, so a variety of tools are often needed. Because too much or too little moisture can be destructive, it is of particular interest to auditors, HVAC technicians, and roofers. Moisture meters can be invasive (pin type) or non-invasive (pin less) and used for anything for verifying the moisture of concrete, drywall, wood, and roofing materials. Several of these units can even go several inches into a wall cavity to measure moisture levels in insulation through drywall. Need more help with you selection? Contact us for assistance.
