Summary

The equilibrium moisture content (EMC) of yellow-poplar sapwood was experimentally determined at dry bulb temperatures from 88 to 116°C and wet bulb temperatures from 77 to 99°C at atmospheric pressure. EMC values were within 1.3 percent moisture content of theoretical values reported in the literature. A high temperature psychrometer, capable of handling humid air at dry bulb temperatures to 177°C, was designed and constructed to accurately measure the humidity during evaluation of EMC's.
