Available from IDM Instruments , Nomura Shoji Sonic Sheet Tester (SST) is used for analysing fibre / molecular orientation of sheets, such as paper and plastic film, with the technique of ultrasonic propagation velocity measurement.

The result of SST analysis has a good correlation with young’s modulus which represents tensile stiffness.

Fibre / molecular orientation, as well as tensile stiffness is an important property of paper and film sheet for many applications, such as high speed and precise colour printing to keep good run-ability and converting to strong corrugated paper box structure.

The SST measuring operation and data analysis is all done via a computer program. Single sheet of A4 size or similar size is suitable for single sheet measurement. All key measured values and graph are displayed on the program for 15 seconds after the measurement has been taken.

The SST can also be purchased with an optional automatic feeding unit, in which both CD and MD profile measurements can be taken.
