## Long description

The FLIR MR40 is a pocket-sized, rugged moisture meter pen for quick measurement of moisture content in wood and other building materials. It combines a simple LCD display, integrated replaceable pins, and an integrated flashlight to provide reliable moisture checks for builders, inspectors, technicians, pest-control specialists, roofers and flooring contractors. The device uses electrical resistance to report moisture content in a 5%–60% range and includes a hold function and a pin calibration check located in the cap.
Advantages
The MR40 is compact and lightweight, designed for portability and field use with splash-proof IP54 protection and drop resistance from 3 meters. It offers clear, fast readouts on an LCD, audible range signaling, a battery condition indicator and long battery life. The unit ships with replaceable pins (four included) and provides a simple calibration/pin-check feature for reliable measurements.
