MO5xA-Series Moisture Meters
Moisture Detection Made Easy
Extech MO5xA-Series Moisture Meters deliver fast, accurate detection with pin and pinless modes—quickly find hidden moisture in walls, floors, and ceilings.
High-Contrast Color LCD
These Moisture Meters feature a bright backlight that ensures readings remain clear and easy to view in any lighting condition—From dark, confined spaces to bright jobsite environments.
Detect Moisture Across Critical Surfaces
Displays moisture levels in wood and building materials such as wall board, sheet rock, cardboard plaster, concrete, and mortar
Audible Alert
The MO5xA-Series uses an increasing "beep" rate to indicate rising moisture levels, allowing users to quickly assess conditions without constantly checking the disply.
Work More Efficiently
Scan large areas quickly, confirm readings instantly, and move on—without switching tools or second-guessing results.
