Product description: Inductive humidity meter - hygrometer - FNIRSI WMT-10
The FNIRSI WMT-10 is a modern, pinless inductive hygrometer designed for quick and precise moisture measurement in building materials and wood. Thanks to non-contact technology, the device does not require inserting probes, which allows the tested surface to remain intact . The meter offers a wide measurement range from 0% to 75% and high accuracy with an error of ±1.5% . A large, easy-to-read 2.4" TFT screen ensures easy data reading, while color DRY/MID/WET indicators facilitate quick assessment of moisture levels . A built-in audible and visual alarm notifies when set thresholds are exceeded. Thanks to its compact design, LED flashlight, and 1000 mAh battery, the device is suitable for both the workshop and construction site.

Measures moisture in plaster walls (0% to 25%), brick walls (0% to 43%), softwood (0% to 75%) and hardwood (0% to 75%).

Moisture measurement modes for wood and walls
The FNIRSI WMT-10 offers four dedicated measurement modes, allowing the device to adapt its reading characteristics to the material being tested. For wood, there are modes for softwood and hardwood ranging from 0% to 75%. For building materials, there are modes for plaster walls (from 0% to 25%) and brick walls (from 0% to 43%). This solution facilitates obtaining reliable results without the need to interfere with the surface. Additionally, clear DRY / MID / WET markings allow for quick assessment of moisture levels, while visual and audible alarms inform when set thresholds are exceeded.
Practical applications
- Moisture control of structural, carpentry and firewood
- Detection of moisture in walls, plaster, concrete and brick
- Assessment of the readiness of the surface for painting, plastering or gluing
- Diagnostics in renovation works and technical inspections
