The short answer is yes, but usually to a very small extent in needle gauges. As the wood temperature increased, its electrical resistance decreased, resulting in an increase in the indicated %MC for this sample. For field conditions, if the temperature of the tested wood sample is between 50°F (10°C) and 90°F (32.2°C), there is no need to correct the temperature reading results.
When measuring wood materials that exceed these temperature values, and the meter itself has no built-in temperature correction, you can use the temperature correction chart to find the correction (Delmhorst provides these corrections for every hygrometer).
Needleless gauge readings do not measure resistance, so their readings are not affected by wood temperature unless the sample is completely frozen.
