Humidity testers for wood
At PCE-Group you will find diverse humidity testers for wood to determine absolute humidity in different wood types. With the help of the humidity testers for wood you will be able to measure with high accuracy humidity in rolled products, forestry wood, slats, beams, plywood, panels, conglomerates, main beams, window frames, etc. . There are two ways of measuring humidity: with or without damaging the material. Humidity testers for wood are characteristic by the measuring principle and the humidity sensors that can be adapted to them. Some humidity testers for wood have special characteristics such as an automatic compensation of temperature. Besides, data can be stored and transferred to a PC or portable computer or characteristic curves can be programmed for specific wood types (only with the model FMD). There are many characteristic curves stored depending on the tester model (oak, beech, birch, poplar, mahogany. Our highest quality tester model has 500 easy to select characteristic curves stored to ensure its high accuracy at measuring. If you don't find the humidity testers for wood you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our measuring instruments.

You will find technical specifications of our humidity testers for wood at the following links:

- PCE-HGP humidity testers for wood
  (testers to measure both relative and absolute humidity as well as temperature)

- FMW-T humidity testers for wood
  (they have stored many characteristic curves)

- FMW-B humidity testers for wood  
  (like the FMW-T humidity testers but with a sensor)

- FMC humidity testers for wood 
  (with different electrodes, compensation of temperature)

- FME humidity testers for wood  
  (like the FMC model but with automatic compensation of temperature)

- FMD humidity testers for wood 
  (programmable characteristic curves. Measuring results can be transferred to a PC)

- PCE-WT1 humidity testers for wood
  (to determine accurately absolute humidity of sawdust)

- PCE-MB 100 humidity testers for wood
  (scales to measure humidity, they are used in industry and laboratories)

FME and FMD humidity testers for wood have an official certificate form the State Verification institution (MPA) in Stuttgart (Germany). As these testers have a certification which says they have passed the intensive control of materials, their high quality is ensured.

FME testers for humidity in wood fulfil all the requirements to be used in humidity controls of wood pillar containments. FME humidity meters have been integrated in the MPA list (Otto-Fraf-Institut) of the most qualified humidity testers for wood.

The electronic measurement of the FMD humidity testers is like the FME one. Both humidity testers of wood are different each other by the data protocol and the additional functions of the FMD humidity testers. Here you will find a description of the different measuring methods.

General information about moisture content in wood: Moisture content in wood is defined as the amount of water in the wood cells in relation to its dry part. Moisture content is displayed in %.  Moisture content can affect both i technical and mechanical qualities of wood. Wood becomes more flexible with an specific moisture content and more resistant against parasite and fungal infections.  When wood is totally dry (0% of moisture content) it is called anhydrous. Wood which is not exposed to direct dampening (rain or ground humidity) with the time has a a compensation according to relative humidity and temperature. Relative humidity in a room goes from 6 to 10% while moisture content in wood (when there is not a direct exposition) can go from 8 to 16%. Extreme situations allow variations in both directions. Slice wood can have more than 100 % of moisture content. Depending on the wood type, wood under 30% of moisture content has a smaller size. When this happens all the water of the cells disappears ant it goes to the cell walls. This water becomes to evaporate and the cell is contracted. This process is different when water is absorbed (change of moisture content) because of the wood size is higher. The previously mentioned humidity detectors can help you to get quick and accurate results regarding moisture content.
