Extech Instruments MO50 User Manual page 2

Introduction
Thank you for selecting the Extech MO50 Moisture Meter. The compact
MO50 takes quick moisture level reference measurements (in percent %) on
wood and building materials. The MO50 is simple to operate and offers meas-
urement digits, audible tones, and 'moisture drop' icons to indicate moisture.
The MO50 is ideal for building restoration projects and applications where
moisture detection on floors and under carpets is critical. It is also a great tool
for analyzing the after-effects of water leakage behind walls and in ceilings.
This meter is shipped fully tested and calibrated and, with proper use, will pro-
vide years of reliable service. Please visit our website (www.extech.com) to
