WDH-318KC Moisture Indicator

Digital material moisture meter for non-destructive moisture measurement of wood and building materials

The WDH-318KC moisture indicator is a precise digital material moisture meter for fast and non-destructive measurement of moisture in wood, walls, ceilings, floors, and masonry. With a measuring depth of up to 20 mm, a digital LCD screen with backlight, and a clear LED bar graph, moisture distribution can be checked reliably.

The compact WDH-318KC moisture meter is particularly suitable for tradespeople, construction companies, expert surveyors, restoration firms, and DIY enthusiasts. It enables quick spot checks directly on-site without damaging the material through drilling or measuring probes.

Ideal for building drying and damage restoration:
The WDH-318KC allows for quick verification of drying progress after water damage, leaks, or construction moisture. Its non-destructive high-frequency measurement allows for the inspection of material areas up to a depth of 20 mm.

Key advantages of the WDH-318KC

  • Non-destructive moisture measurement – no drilling or measuring needles required.
  • Measuring depth up to 20 mm – allows for the inspection of deeper material layers.
  • For wood and building materials – suitable for softwood, hardwood, masonry, walls, ceilings, and floors.
  • Four measuring modes – different settings for hardwood, softwood, masonry, as well as walls, ceilings, and floors.
  • Digital LCD display – clear representation of the measured value.
  • LED bar graph – quick visual assessment of the measured moisture.
  • Backlight – good readability even in poor lighting conditions.
  • Data-hold function – measurement value can be frozen for easy reading.
  • Automatic calibration – ready to use immediately after switching on.
  • Audible alarm – warning for readings outside the intended measuring range.
  • Auto-shutoff – switches off automatically after 2 minutes of inactivity.
  • Compact design – only approx. 186 g including battery.
  • Battery warning indicator – informs you in good time about a low battery level.

Non-destructive moisture meter for building materials

The WDH-318KC uses a non-destructive high-frequency measurement method. This allows moisture levels to be checked without damaging the surface of walls, floors, ceilings, or wooden parts.

This is a major advantage, especially for high-quality surfaces, finished interiors, and existing buildings. Unlike measuring devices with insertion electrodes, no holes need to be made in the material.

Quick preliminary check:
The WDH-318KC is excellent for quick control and comparative measurements. For critical or court-proof moisture measurements, further measurement methods may be required depending on the material and application.

Moisture meter for wood

With the WDH-318KC wood moisture meter, the moisture content of soft and hardwood can be checked quickly. This is useful, for example, before processing, during installation, or when assessing wooden components.

The measuring range reaches up to 53% for softwood and up to 35% for hardwood. This allows both normal material states and significantly increased moisture levels to be detected.

Measuring moisture in walls, ceilings, and floors

During damage restoration and building drying, it is important to regularly check the development of material moisture. The WDH-318KC provides a quick overview of which areas still exhibit increased moisture.

Especially after water damage, pipe bursts, or floods, affected areas can be investigated and compared with each other. Even in new buildings and renovations, the drying progress can be monitored before further work is carried out.

  • Moisture measurement on walls
  • Inspection of ceilings and floors
  • Investigation of masonry
  • Inspection of wooden components
  • Comparative measurements during building drying
  • Preliminary check before subsequent work

Four measuring modes for different materials

The WDH-318KC moisture indicator has four different measuring modes. This allows the measurement procedure to be adapted to different materials and areas of application.

Measuring mode Area of application
Softwood Measurement of material moisture for various types of softwood.
Hardwood Measurement of material moisture for various types of hardwood.
Masonry Inspection of moisture distribution in masonry.
Walls / Ceilings / Floors Relative moisture assessment for various mineral building materials and components.

WDH-318KC for damage restoration and building drying

After water damage, it is often not enough to just assess the visible surface. Moisture can spread within building materials and also be present in deeper layers.

With the WDH-318KC, affected areas can be quickly checked and different measurement points can be compared with each other. This makes it easier to monitor the progress of a drying process.

Recommendation for building drying:
Use the WDH-318KC to regularly check the drying progress. For the actual removal of large quantities of moisture, a combination with a suitable dehumidifier or professional building dryer is recommended.

Use cases for the WDH-318KC

Area of application Application
Water damage Inspection of moisture in affected walls, floors, and ceilings.
Building drying Monitoring the drying progress during dehumidification.
New construction Checking material moisture before further construction and finishing work.
Renovation Localization and comparison of damp areas during renovation work.
Wood processing Checking wood moisture before processing or installation.
Damage assessment Quick preliminary check and documentation of moisture areas on-site.
