The MO50 integrates a pair of slender contact pins that you insert into the material under test—be it wood, drywall, plaster, concrete or mortar—to get a rapid moisture-percentage reading. The LCD displays the numeric result (in percent) and uses one to three water-drop icons to visually indicate whether conditions are low, medium or high moisture. Simultaneously, an audible tone beeps at a rate that increases as moisture levels rise, giving audible confirmation of wet conditions. A material-select button allows switching between “wood mode” and “building‐material mode” (each with their own range). Additional features include a display-lock function to freeze the current reading, a low-battery indicator, and auto power-off to conserve energy. The device ships complete with test pins installed, a protective cap, and a 9 V battery. Its slender housing makes it convenient for field use, behind walls or beneath flooring. Overall, it’s built for fast, practical measurement in the field rather than deep diagnostics. Features Pin-type contact measurement of moisture in wood and building materials. Material selection between wood (approx. 5%–50% moisture) and other building materials (~1.5%–33%). Audible alert: tone rate increases as moisture rises and visual “drop” icons for low, medium, and high moisture levels. Display lock function to freeze readings, and low battery indicator for convenience. Auto power-off feature conserves battery life during inactivity. Compact and portable design — dimensions approx. 170 × 65 × 30 mm (6.7 × 2.6 × 1.2″) and weight about 120 g without battery. High resolution of 0.1% moisture content ensures precise readings. Supplied complete with contact pins, protective cap, and a 9 V battery. Ideal for restoration work, flooring, wall inspections, drywall, or carpet moisture detection. Simple, easy-to-operate interface with quick start-up, material selection, and testing via pins. Includes 4 Replacement Pins Protective Cap 9V Battery
