The ERNST STE-B calibrated pin system replaces the impact bar system giving a greater versatility and high accuracy.
The indentations can be made very quickly even by an unskilled operator.
The indentation can be read immediately, or at a later time by an inspector.
Due to the fact that with the calibrated pin system only one reading of the indentation on the piece is necessary, error possibilities are cut by 50% compared to the impact bar system.
The comparison errors are eliminated and the resulting accuracy is comparable to the bench hardness testers.
