木材水分仪校准方法研究

Research on the calibration method of wood moisture meters

根据木材含水率的定义,通过大量实验,确定了可迅速定值、重复使用的高精度木材含水率试样,试样的含水率范围为7%～22%,扩展不确定度达到0 7%H2O,从而解决了各类木材水分仪的校准问题.

Based on the definition of the wood moisture and large amount of experiments, the high precision samples of wood moisture were developed, which can be used repeatedly and whose value can be determined rapidly. The moisture range of the samples is from 7% to 22% and its expanding uncertainty is 0.7%.Thereby the problem of the calibration of all kinds of wood moisture meters is solved.
