The Extech MO57A is a professional, non-destructive moisture meter designed for the rapid detection of moisture in wood and a wide variety of building materials. Thanks to its spherical, pinless sensor, the device glides gently over surfaces, allowing for measurements without damaging the material. Moisture detection is performed via electromagnetic signals and is ideal for applications in construction, renovations, and the analysis of water damage.
The MO57A measures moisture to a depth of 10.2 cm and displays relative readings on an easy-to-read color LCD. In addition, audible warning signals with three intensity levels and moisture symbols facilitate quick evaluation of the measurement results. Thanks to automatic calibration, a hold function, and automatic shut-off, the device offers high ease of use for professional users.
