How to check the moisture content of wood without a meter?

Measuring the moisture content of wood without a meter can prove challenging. Fortunately, terahertz time-domain spectroscopy presents an efficient alternative. Here are steps to effectively determine moisture content using this method:

• Gather Materials: Acquire a terahertz time-domain spectrometer system and a wood sample.
• Sample Preparation: Prepare a thin slice (1-2 mm) from the wood sample to ensure proper terahertz penetration.
• Spectroscopic Measurement: Position the wood sample in the measurement cell of the spectrometer. Initiate the measurement to obtain a time-domain waveform.
• Data Analysis: Employ mathematical algorithms to analyze the time-domain waveform and extract the complex permittivity of the wood sample.
• Moisture Calculation: Correlate the extracted permittivity with the moisture content based on established calibration models.

By following these steps, you can utilize terahertz time-domain spectroscopy to assess the moisture content of wood accurately and non-destructively.
