Brookhuis Micro-Electronics B.V. of Enschede (the Netherlands) is an innovative, leading manufacturer of precise wood and construction moisture meters. The range of instruments produced by Brookhuis Micro-Electronics includes moisture meters that operate according to the resistance method (types FMC, FMD, FME and MCM) and moisture meters that operate according to the capacitative method (FMW and FMI). All these instruments meet the high industrial demands placed on reliable, precise instruments.

The most important features of the Brookhuis Micro‑Electronics moisture meters are:

  • Reproducible measurement results thanks to the use of special measurement electronics (hybrid sensor).
  • Calibration lines for wood and construction materials, fine-tuned to the specific qualities of the materials to be measured (software) and the possibility of expanding and improving the calibration lines (update).
  • Easy operation (intelligent design).

Thanks to these distinctive features, Brookhuis moisture meters are known and used around the world in the wood and construction industry.

Through close co-operation with wood and construction institutes in the Netherlands and abroad, we have gained extensive knowledge and experience of measuring moisture content. That's one reason Brookhuis Micro-Electronics has such a large number of calibration lines available for wood and construction materials.

 
Calibration lines - Reference values
 

The reference values determine the course of the calibration lines programmed in the moisture meters. These reference values originate from scientific research conducted by Brookhuis Micro-Electronics and the following institutions:

  • Building Technology (VTT) - Finland
  • Bundesforschungsanstalt für Forst- und Holzwirtschaft (BFH) - Germany
  • Danish Technological Insitute (DTI) - Denmark
  • Forest Research Institute Malaysia (FRIM) - Malaysia
  • Forest Research Institute - New Zealand
  • Forestry and Forest Products (CSIRO) - Australia
  • Forintek Canada Corporation - Canada
  • Norwegian Institute of Technology (NTI) - Norway
  • Stichting Keuringsbureau Hout (SKH) - The Netherlands
  • SHR Hout Research - The Netherlands
  • Swedish Institute for Wood Technology Research (Trätek) - Sweden
  • TNO Building and Construction Research (TNO Bouw) - The Netherlands
  • United States Department of Agriculture (USDA) - USA
 
FMI In-Line Moisture Meter
 

The FMI In-line system of Brookhuis Micro-Electronics for longitudinal feeding makes it possible to measure wood moisture content without contact with the wood. The FMI “Type L” can measure the moisture content at a speed to 600 metres a minute and measures along the full length of the board 400 times a second.  The FMI System Type L includes a Control Unit and a U Shaped Feed-through Sensor.

The FMI type X can measure the moisture content at a speed of 200 boards a minute and measures 400 times a second.

The FMI system type X consist of a control unit and one or more sensors.

The control unit is microprocessor-controlled. Data (the wood species, the dimensions, the specific weight, the maximum and minimum admissible moisture contents of the wood and the action which should follow when the moisture content is outside the limits) can be programmed into product programs by the user. The FMI system can be integrated into production lines for sorting, marking or ejecting the wood.

Microprocessor controlled system

The control unit is provided with an extensive software program. It is menu-driven and with the help of function keys simple operation is guaranteed. The data can either be printed with a printer or processed with a PC. Extensive reports and statistics can be produced in combination with programs like MS Excel and Access

FMD6 Moisture meter - Accuracy with many possibilities
 

FMD6 measures the moisture content with a probe which is placed in or onto the material to be measured. The FMD6 has a memory for measuring reports. Each report includes the data of the measured material as well as a statistical survey and a reliability interval. Stored values can be printed or processed with a personal computer using the FMD-Print program.

Minimum and maximum moisture content can be set for quick selection

Unique features are the calibration lines of many wood species and building materials that are programmed in the FMD6, as well as the many calibration lines which can be programmed by the user.

FMD6 is the fully renewed model of FMD and offers interesting new features as:

  • Wood species includes botanical names
  • Updating new calibration lines by e-mail
  • Improved operation
  • Extended memory for 2000 readings
  • An audible alarm
  • USB connection possible

The FMD6 is the ideal instrument for the professional who wants to measure, store and register moisture measurements of various wood species, construction materials and paper, for the benefit of quality control.

 
FMW Contact Free Moisture meter
 

Microprocessor-controlled moisture meter suitable for measuring wood and construction materials .

The FMW measures the moisture level when the back side of the instrument is held against the material to be measured for half a second. Because the specific density of the wood can be entered in the FMW all types of wood can be measured extremely accurately. The FMW can be set for wood ranging between 250 and 1100 kg/m³.

The FMW can be supplemented with a calibration set allowing you to check the meter for ISO 9000/9001conformity at any time.Because the FMW measures the wood just by touching it, and due to the high-frequency measuring technology, the FMW moisture meter will take measurements without damaging paint layers or building plastic

For measuring contruction materials the FMW has a relative scale. This makes the FMW moisture meter ideal for final and rapid inspections!
