Precigrader is an acoustic on-line strength grading system. The system is installed in over 150 mills. It is used to determine common commercial grades in North America, including 1650 and 2100. A spring-loaded impact mechanism strikes the lumber as it passes. The resulting vibration is captured by microphones to determine the appropriate MSR grade.
