ACCURATE DETECTIONThe moisture meter uses needle-free high-frequency electromagnetic wave induction detection, which can complete the detection without causing any damage to the object. High-precision measurement is ensured with an accuracy of 4%. Accurate measurement and fast response. Note: Please dry the surface of the object before detection to get more accurate results. EASY TO USEThe moisture meter is easy to use. Just press the power button to turn it on, select the mode and density level, and point the sensor plate at the object you want to measure. When the value is stable, the measurement is completed. Long press the « HOLD » button to lock the value, making it easy to record readings. MULTIPLE MODES & DENSITY LEVELS Professional moisture meters have developed different measurement modes and density levels based on different materials. Including softwood (0-60%), hardwood (0-36%), wall (0-20%), masonry (0-33%) and softwood density levels from 1 to 9. And you can design the humidity alarm value by yourself. When the value reaches or exceeds the set alarm value, the buzzer will sound an alarm. PERFECT DESIGN The professional humidity meter uses a high-definition LCD display, which allows you to view various data more intuitively. There are specific colors to display the humidity status of the detected object, which simplifies your detection. And it has an automatic shutdown function after 5 minutes of inactivity to extend battery life.
