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 measurement digits, audible tones and ‘moisture drop’
icons to indicate moisture level content.

The MO50 is ideal for building restoration projects and applications where moisture detection on
floors and under carpets is critical. The MO50 is 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 provide years of
reliable service. Please visit our website (www.extech.com) to check for the latest version of this
