Contractors and home inspectors, this behind-the-wall probe is exactly what you need for accurate moisture detection! With 7-inch insulated pins (except at the tips), this tool can reach up to 6 inches deep into materials to check for moisture where you can't see it. The insulated design prevents false readings and ensures you're getting accurate moisture measurements. It's perfect for checking roofs, insulation, EIFS systems, drywall, and other building materials where hidden moisture could cause serious problems. The extended reach means you can test deep into materials without damaging surfaces unnecessarily. There's also a version available with a tapped handle for those hard-to-reach areas where standard probes won't fit. This isn't just for professionals either - DIY homeowners can use it to check for leaks, water damage, or moisture issues before they become major problems. The 90-day warranty gives you peace of mind about the quality. Whether you're inspecting a property, troubleshooting a leak, or doing routine maintenance checks, this probe delivers the accuracy and reach you need. It's one of those specialized tools that seems simple but can save you thousands in water damage repairs by catching problems early.
