RYOBI Pinless Moisture Meter;

Knowing the moisture levels in your walls, wood, and masonry can give you an estimate of the potential for mold growth throughout your home. To help you get an easy reading on these moisture levels, use the E49MM01 from Ryobi. It's very easy to use. Simply hold the sensor over whatever you're trying to read, set the device to read whatever material you're using (it's good for wood, drywall, and masonry), and look at the LED screen for a percentage. Additionally, you can listen to the audible alerts the device sends off. They change in frequency as you run into higher levels. By using both sight and sound, you're sure to have an accurate measurement. It doesn't use any pins, so you can run this over your delicate surfaces without scuffing them up. For a solid moisture meter to use around the home or diy workshop, the E49MM01 from Ryobi is a solid choice.
