No material-specific probes are required.\u003c\/p\u003e\n\u003ch2\u003eImportant Limitations\u003c\/h2\u003e\n\u003cp\u003eReadings are comparative material-moisture indications, not laboratory moisture-content certification or a leak diagnosis. Results can vary with material density, coatings, salts, metal behind the sensing area, surface water, temperature, and how fully the sensor contacts the material. Documentation uses slightly different names for some material presets; select the closest on-device mode and establish a dry reference on the same material whenever possible.\u003c\/p\u003e\n\u003ch2\u003eSafety \u0026amp; Use Notes\u003c\/h2\u003e\n\u003cp\u003eDo not use in flammable or explosive environments. Keep the instrument dry and away from corrosive liquids. Dry visible surface water before testing, and keep hands and metal objects away from the rear sensing area while measuring. Use only the specified charging method.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the WMT-10 use pins?\u003c\/strong\u003e\u003cbr\u003eNo. It uses an inductive sensor for non-destructive, surface-based screening.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it confirm a hidden leak or certify moisture content?\u003c\/strong\u003e\u003cbr\u003eNo. Use it to compare conditions and identify areas needing further investigation. Verification may require an appropriate invasive meter or professional assessment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy may the displayed percent differ on different materials?\u003c\/strong\u003e\u003cbr\u003eThe value depends on the selected material preset and the material’s properties. Compare readings only within the same material and mode.\u003c\/p\u003e\n\u003ch2\u003eUser Manual \u0026amp; Downloads\u003c\/h2\u003e\n\u003cp\u003eThe English WMT-10 manual has been identified and is pending Shopify file upload.
