Hygromètre Fnirsi WMT-10 hygromètre numérique à haute précision

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.

Suitable for

• Measuring moisture in softwood and hardwood
• Testing brick, stone and compacted ground surfaces
• Checking plaster, cement, concrete and powdered wall surfaces
• Use on construction sites, renovation and carpentry projects

How to use

Switch on the meter and select the appropriate measurement mode for the material being tested (Softwood, Hardwood, Masonry or Powdered Wall). Place the measuring panel flat against the surface and wait for the reading to stabilise on the screen. Use the HOLD function to freeze a measurement, and store results in memory if comparison with previous readings is required. Charge the device via the Type-C port before extended use.

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.
