The Fnirsi WMT-10 is an advanced non-invasive moisture meter and hygrometer designed for fast, accurate testing without surface damage. Utilizing induction technology and an electromagnetic wave sensor, it features four dedicated operating modes for softwood, hardwood, masonry, and powdered walls. With a 2.4-inch TFT color screen, a wide measurement range up to 75%, 0.1% resolution, memory for 30 readings, and a built-in 1000 mAh battery, this tool is ideal for construction, renovation, and carpentry applications.
Advantages
This non-invasive moisture meter provides reliable and rapid readings without puncturing or damaging the surface being tested. Its induction technology and sensitive electromagnetic wave sensor ensure precise evaluations across various materials. The large 2.4-inch TFT color screen offers excellent visibility even in dark environments, supported by a built-in flashlight for working in low-light conditions. Ergonomically designed with a non-slip silicone coating and soft plastic buttons, the device ensures a secure and comfortable grip during extended use. Additionally, advanced functions such as light and audible limit alarms, a measurement hold option, and internal storage for up to 30 readings make data tracking and comparison straightforward and efficient.
Suitable for
- Testing moisture levels in softwood such as beech, spruce, birch, and cherry
- Checking moisture content in hardwood including teak, walnut, ash, and oak
- Assessing masonry surfaces like brick, stone, and compacted ground
- Measuring plaster and concrete in powdered walls, ceilings, and floors
- Professional construction, renovation, carpentry, and finishing trades
When it may not be suitable
This device may not be suitable for applications requiring subsurface moisture detection beyond a depth of 17 mm, as its maximum detection depth is limited. Furthermore, because it relies on non-invasive electromagnetic induction rather than pin probes, it cannot determine moisture levels at specific internal core depths of thick timber or dense building structures.

How to use
To begin using the meter, power on the device and select the appropriate operating mode corresponding to your target material, choosing from softwood, hardwood, masonry, or powdered wall settings. Place the measuring panel flat and firmly against the surface to be tested. Read the measurement value directly from the color screen. Utilize the hold function if you need to freeze the reading on the display, and save measurements to the internal memory when comparing multiple test spots. Recharge the battery using the USB-C cable when power is low.
What to consider before purchase
- Verify that the 17 mm maximum detection depth meets your specific inspection requirements
- Check the material compatibility to ensure your target surfaces match the four available operating modes
- Consider the built-in 1000 mAh battery capacity and ensure convenient access to USB-C charging during long work shifts
Usage recommendations: Always ensure the sensor panel makes direct and flat contact with the tested surface for the most accurate results. Store the device in a dry environment within the specified operating temperature range when not in use, and regularly check the battery level to maintain uninterrupted operation on the job site.
