Description
The FLIR MR40 Moisture Pen is a pocket pin moisture meter with a built-in flashlight, made for quick moisture checks on wood and building materials anywhere on the job.
The MR40 measures moisture content from 5% to 60% with an audible alarm that speeds up as moisture rises, so you can scan studs, subfloors, and drywall quickly. Integrated pins, a work light, and a pen-sized waterproof housing make it the meter that is always in the pocket when you need a first answer.
- Pocket-portable, rugged 2-pin, single-scale moisture meter for wood and common building materials
- Integrated flashlight (~40 lumens) eliminates the need to carry a separate light
- Audible indication of measured range: slow beep at 5–12%, faster at 13–60%, fastest above 60%
- Calibration/pin check (16%) integrated in the cap
- Measurement Hold function and clear LCD display
- Replaceable pins — a second set is included in the box
- IP54 splash-proof and 3 m drop tested; small enough to carry in a pocket and measure in tight spaces
Typical Applications
- Restoration first response
- Building inspections
