Precise, reliable and features cutting edge technology: That is how you like to work. Then the Wöhler HF 550 is right for you: Just one instrument is required to measure the moisture of firewood logs and bulk materials. The moisture content of solid fuels is often the cause for complaints when monitoring the threshold values of household fireplaces. However, using fuels with an appropriate moisture content can significantly reduce the emission of ollutants. This is where the Wöhler HF 550 provides ideal support: It even measures the moisture of wood chips in conformance with applicable standards. The instrument automatically recognizes if a probe is connected to measure the moisture of firewood logs or bulk materials. It switches to the corresponding menu and assists the measurement process with straightforward information. That guarantees the measurement conforms to the specifications contained in VDI 4206, Part 4 – with very little effort.


  • Unconditional versatility: Measure moisture of firewood logs and bulk materials with just one instrument
  • Unconditionally user-friendly: Intuitive menu navigation, color display, integrated data management
  • Unconditionally robust: Robust instrument – robust probe

Wohler FW 550 Moisture Scale Bulk Material

It is now possible to determine the moisture of bulk materials such as wood chips and pellets. The Moisture Scale is connected to the measuring instrument to determine the moisture content. The instrument automatically recognizes the scales and switches to the bulk material menu. Operating errors are virtually impossible, because the instructions in the display reliably guide the user through the standards-compliant measurement process. The Moisture Scale initially determines the mass of the bulk material filled and afterwards the moisture. This process leads to a density-compensated result and, as a consequence, to greater accuracy.
