General Tools MMD4E is a must-have for woodworkers, and contractors. It’s a pin-type meter designed to detect moisture levels in wood and building materials (drywall, brick, concrete, etc.), helping you identify potential leaks or ensure wood is dry enough for use.

  • Easy-to-Read LCD: Large, clear display for quick readings.

  • Dual Mode: Separate settings for wood and other building materials.

  • Visual/Audible Alerts: LED lights (Green, Yellow, Red) and an audible beep indicate moisture levels.

  • Data Hold: "Hold" button freezes the measurement on the screen.

  • Protective Cap: Includes a cap to protect the pins when not in use.
