Moisture Meter, Combination Pin/Pinless
Extech MO260 Combination Pin/Pinless Moisture Meter
Dual-sensor moisture diagnostics for comprehensive structural and material evaluation.
The Extech MO260 is a highly versatile diagnostic instrument engineered for structural engineers, building inspectors, and materials testing professionals. By integrating both non-destructive pinless scanning and traditional contact-pin measurement into a single, robust device, it provides the definitive data required for rigorous moisture auditing in wood, masonry, and varied building materials.
Whether conducting rapid baseline assessments across large surface areas or isolating specific zones of subsurface moisture intrusion, this meter delivers the flexibility and high-precision accuracy demanded by advanced facility diagnostics and structural restoration projects.
Key Technical Capabilities
Dual Measurement Modality: Features advanced electromagnetic pinless technology to scan for moisture up to 22mm (0.75") below the surface without causing cosmetic damage, alongside replaceable measuring pins for exact, localized contact readings.
Direct Material Metrics: Accurately measures % WME (Wood Moisture Equivalent) in wood while delivering relative moisture readings for sheetrock, concrete, and mortar.
Multi-Tiered Indication: Equipped with a high-visibility, backlit digital LCD screen paired with a multi-color LED bar graph that instantly categorizes moisture levels into dry, moderate, or damp states.
Integrated Calibration Verification: Built with a calibration check integrated directly into the protective sensor cap, allowing technicians to immediately verify instrument accuracy in the field before critical assessments.
Advanced Operational Features: Includes a Data Hold function to freeze active readings during awkward inspections, alongside an automatic power-off feature to optimize battery life across extended site audits.
