The FLIR MR40 is a compact, robust moisture meter with two pens, a single scale and an integrated flashlight for wood and other common building materials. This enables experts to quickly and reliably identify damp areas during construction work, conversions, roof and floor work in residential buildings and pest control and determine their moisture content. Thanks to its pen-like design, you can always store the FLIR MR40 in your pocket and take it with you wherever you go.
