Standard QQI - Model 3C2-234
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.
