The Extech MO55W Wireless Datalogging Pin or Pinless Moisture Meter quickly measures the moisture content in wood and other building materials with either choice of Pinless (non-invasive) or Direct Pin method measurement. Using the wireless feature, Bluetooth Datalogging Module, and the free ExView W-Series App, readings can be transmitted in real time to a smart device. Store over 15K readings for wireless transfer to generate a report/data analysis, add notes and readings to photos taken from a smart device camera, and use a smart device as a second display for easy viewing or sharing. The MO55W is simple to operate and uses icons that indicate moisture content and alerts when moisture levels exceed programmed limits.
