ASTM Pie Gauge
ASTM PI Field Indicator is used to check the presence and direction of magnetic field. It comes with a non ferrous handle for easy placement on the job. Artificial cracks are generated in an octagonal test piece. Lines which are perpendicular to the magnetic field give indications. Meets Requirements of ASTM E1444.

Quantitative Quality Indicators Shims
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 very 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. Meet Requirements of ASTM E1444.
