Moisture Pen + Flashlight
The FLIR MR40 is a pocket-portable, rugged 2-pin, single-
scale moisture meter with an integrated flashlight for wood
and common building materials – ideal for builders, building
inspectors, remodelers, moisture remediation technicians,
pest control professionals, and residential roofing and flooring
contractors. Providing reliable and accurate measurements
offered at a highly affordable price point, MR40 is a quick and
easy-to-use tool to find and quantify moisture content.
