Hello, thank you for reaching out. There is no way to turn off the audible alert on this meter.
Our moisture meters are not capable of reading accurately in cinder black due to the increased conductivity in concrete. This is similar to the reaction you will see when scanning metal; these units are reacting to the conductivity in the material, and not to any moisture, making the readings untrustworthy.
Yes — the Pin-Type Digital Moisture Meter with LCD Display is adequate for checking moisture under your sink, including particle board, cabinets, and wall spaces.
To measure wood, press and hold the power button, press "Mode" to select "Wood", remove the cover on the end to expose the pins, press the pins into the wood either on the end of a split piece of wood or on its side. The inside of a freshly split piece is the best place to measure to get the overall moisture content, but the end is ok to get a quick general idea. The display will indicate the moisture content, and a light will indicate whether that is "Low", "Mid", or "High". You can also measure the calibrated resistor inside the cap to assure that it is measuring correctly. An extra set of pins are included in case the test pins are damaged.
The MM7 is designed for use in woodworking, water damage restoration, building construction and home renovation.
The 3% accuracy means that if a reading is showing up as 10%, the moisture content could be anywhere from 7-13%. These meters do have a calibration check as a feature that can be used to see the exact skew of the sensor.
