Moisture meter correction factors for four Brazilian wood species

The species correction factors during moisture content measurement of jatoba (Hymenaea courbaril), mandioquiera (Qualea paraensis), quarubarana (Erisma uncinatum), and quarubatinga (Vochysia lehmanii) were determined for dielectric- and resistance-type moisture meters. When using the dielectric-type moisture meter, the correction factors for mandioquiera and quarubarana range from -3.2 to -1.0 and from -3.0 to -1.3, respectively. For jatoba and quarubatinga, the average correction factors of -4.6 and 0.4, respectively, may be used over the full experimental dielectric meter reading range. When using the resistance-type moisture meter, the correction factors for quarubarana and quarubatinga range from 0.6 to -0.9 and from 0.0 to -1.8, respectively. For jatoba and mandioquiera, the average correction factors of 0.8 and 0.3, respectively, may be used over the full experimental resistance meter reading range.
