WÖHLER HF 550 - WOOD MOISTURE MEASUREMENT
Precise, reliable and with the latest technology: this is our way of working. The Wöhler HF 550 is suitable for: measuring the moisture content of both lump wood and bulk fuel with just one instrument, both options being TÜV-tested.
The moisture content is often the reason for complaints when monitoring the combustion of wood in a fireplace. By choosing fuel with the right moisture content, it is possible to control the emissions of harmful substances. The Wöhler HF 550 offers ideal help here: you can measure the moisture content of the wood chips yourself on site. The device automatically detects whether a probe for measuring the moisture content of lump wood or for measuring the moisture content of bulk fuel is connected. The device automatically changes to the corresponding menu and simply guides you through the measurement. This measurement is guaranteed because the device complies with VDI 4206, part 4. and without the slightest effort.
