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

Thermography is a non-invasive technique that can be used to measure the moisture content of wood. This technique involves using a thermal imaging camera to detect and measure the amount of infrared radiation emitted by the wood. The moisture content of the wood can then be inferred from the temperature readings obtained from the thermal imaging camera. This technique is a reliable and accurate way to measure the moisture content of wood, and it does not require any physical contact with the wood. Furthermore, it can be used to measure the moisture content of wood in real-time, making it a valuable tool for monitoring the drying process of wood. The results obtained from this technique can be used to determine the appropriate time to remove the wood from the drying kiln, ensuring that the wood has reached the desired moisture content.
