The aim of the study was to evaluate the precision of two types of electric moisture meters during the drying process of Eucalyptus grandis boards. Samples were obtained from 14 boards of Eucalyptus grandis and they were dried in electric laboratory oven at 40 ºC of temperature, until the wood achieve 10% of moisture content. During the drying, the moisture content was determined by gravimetric method and simultaneous checks by an electric moisture meter (EMM) and by kiln control system (KCS). The results showed that: (1) the KCS can replace the gravimetric method during the wood drying; (2) the EMM underestimate the real moisture content during the drying of boards and it is not indicate as substitute of the gravimetric method.
