Structural lumber strength classes are determined by the EN-338 norm. The Portable Lumber Grader is designed to grade lumber according to the above norm, that handles two different species classes: deciduous and coniferous including poplar. Grading is based on the modulus of elasticity (MOE) and the average specific gravity of the lumber. The Portable Lumber Grader system determines the MOE and specific gravity as quickly as possible (1 second/lumber).

USAGE INSTRUCTIONS
