1. Maximum specified range is dependent on the fibre saturation point for specific species. Beyond
this point, the reading can only be used as a relative reference value. For more information on fi-
bre saturation please refer to public document ASTM D7438. Accuracy specification is based on
the analysis in J. Fernández-Golfín et al. Actual real-world accuracy depends on a variety of fac-
tors; For more information, refer to public document ASTM D4444, section 6.
2. Accuracy spec. applies to pin probe moisture measurements taken on wood whose temperature
is 20 °C (70 °F). Add 0.1% to the accuracy spec. for each °C below 20 or subtract 0.1 for each °
C above 20.
