## Summary description

Fnirsi WMT-10 is a digital humidity meter (hygrometer) designed to measure relative humidity with high accuracy. The compact device provides clear numerical readings for monitoring indoor climate in homes, offices, greenhouses or storage areas. It is useful for controlling comfort, preventing mold, and protecting sensitive equipment or materials.

## Long description

The FNIRSI WMT-10 is a non-invasive moisture meter that provides fast, high-resolution readings without puncturing surfaces. Using induction technology and an electromagnetic wave sensor, it supports measurements on wood, masonry, plaster and other building materials. A large 2.4-inch color TFT screen with 0.1% resolution and a built-in flashlight ensure readable results in low-light conditions, while a rechargeable battery with USB-C charging supports extended use.
Advantages
The device offers four dedicated measurement modes tuned for softwood, hardwood, masonry and powdered/plastered walls, enabling accurate readings to a depth of 17 mm and a maximum reported moisture of 75%. It includes an extra-wide 40.5 × 40.5 mm measuring sensor, audible and visual alarms for limit exceedance, HOLD to freeze readings and memory for up to 30 measurements. The housing has a non-slip silicone coating and soft plastic buttons for comfortable handling.

Usage recommendations
For consistent results, ensure the measuring panel is clean and in full contact with the tested surface. Allow the surface to reach ambient temperature and avoid measuring through coatings or thick finishes that may affect induction-based readings.
