Quantitative Quality Indicator (QQI) Test Pieces

Quantitative Quality Indicators (QQI) are magnetic particle test pieces with artificial defects used to verify field direction and relative strength. QQI’s are also used to balance multi-directional fields and to increase productivity by minimizing magnetizing shots.  *The QQI indicator shims are packaged in sets of five.
