【WOOD MOISTURE METER】This pinless moisture meter non-destructively detects moisture through the imported sensor on the back. It has no pins and will not damage the material being tested. Rapid detection of various materials by transmitting and receiving high-frequency electromagnetic wave signals to the measurement material. By locating the moisture distribution in wood/walls/floors/ceilings, you can know exactly where the moisture is most concentrated. 【INTELLIGENT EQUIPMENT】The moisture tester has a large LCD color screen and a color analog display bar, making it easy to view measurement results. When the wood moisture reaches 17%, the instrument will automatically alarm, and when the wall moisture exceeds 70%, it will automatically alarm. When the alarm is issued, the instrument will beep and the display bar on the screen will show the red part. 【EASY TO USE】 This hygrometer can detect ambient temperature and humidity, and ℃/℉ temperature display switching function. With data retention function and one-key clearing function, it can save the current measurement value for easy recording. Automatic shutdown after 10 minutes to save battery life. ZERO calibration - Used to detect anomalies in surfaces that must be uniform. 【MEASUREMENT AND APPLICATION】 The wall moisture tester has 4 measurement modes: SOFTWOOD | HARDWOOD | DRYWALL | MASONRY. Can be used to measure all kinds of stone, wood, cement, paper, RVs, caravans. It provides a quick and non-destructive indication of moisture distribution near surfaces and is an excellent tool for homeowners, carpenters, floor inspectors to identify leaks and water intrusion problems. Precautions 1. The storage environment of the instrument should be kept away from high temperature, humidity, corrosive gases or objects. 2. Do not drop or hit the instrument or disassemble the instrument to avoid failure. 3. If there are stains or dust on the surface of the instrument, please clean it with a damp sponge or soft cloth.
