QQI Test Shims

QQI Magnetic Particle Penetrameters

QQI's (Quantitative Quality Indicators) are magnetic particle test pieces with artificial defects used to verify proper field direction and adequate field strength.

QQI's are a valuable tool to be used to establish testing criteria with Multi-Directional 2-D and 3-D type testers and to increase productivity by minimizing magnetizing shots.

QQI's are both thin and flexible to conform to the geometry of the test piece. They must be held in intimate contact with the test piece by either tape or glue.
