Rechargeable Moisture Meter, Moisture Tester, Non-Destructive Measurement, Masonry Moisture Meter with Color LCD Display and Audible Alarm for Walls, Wood, Plaster, Wood Moisture Analysis (20-40

40MM non-destructive measuring depth - The wall moisture meter emits a high-frequency wave that penetrates about 40mm into the masonry, probe length 58MM, measuring range 0.0-100.0, resolution: 0.1%, and moisture measurement does not damage never the surface of the object. The moisture meter has a dual alarm mode: audible and on-screen alarm. Alarm thresholds can be set automatically according to user needs.

Note on use - Before first use, please open the back cover to plug in the battery cable. Please recalibrate for each measurement, press the “MEAS” button after turning on the wood moisture meter and it only needs to wait 3 seconds to complete automatic calibration. As the humidity level of the hand has an influence on the measurement results, the smaller the contact surface between the hand and the device, the higher the value displayed is close to the real value. (the greater the distance from the spherical head)

High-quality HD color display - The wall-mounted material moisture meter is equipped with an HD color display with three colored analog bars and indicates the status "DRY", "RISK" and "WET" by colors "green", "yellow" and "red" respectively. The current measured value can be saved using the “Hold” button. Additionally, it offers maximum and minimum humidity values. The hygrometer can turn off automatically after 30 minutes of inactivity.

Wide range of applications - The moisture meter is suitable for checking the moisture content of wood and building materials (such as wallboard, slate, tiles, cardboard, plaster, concrete and mortar), as well as for repairing leaks, check the humidity level of bedroom walls, floor tiles or caravans, etc. The humidity indicator helps you quickly detect mold and protect the structure of your house or apartment.

Tip 1：Wipe the surface of the measured material dry and clean to get the best results. In addition, the materials to be measured (walls, masonry and wood) are not stacked or stored on more humid materials.

Tip 2: The wall moisture meter penetrates up to 1.6 inches deep, so wetter materials below the material to be measured can also influence the readings, e.g. metal nails, workbenches, hands, etc. Make sure that there is no metal within a 2 inch radius of the measurement.
