title: A microprocessor-based system for readout of x-ray penetrameter films.
abstract: A microprocessor-based instrument has been constructed which allows rapid analysis of a standard penetrameter film using a handheld probe. Compensation for non-uniformity of the X-ray viewing box used as a light source is automatic and there is a paper record of procedures and results. Calibration data for the penetrameter can be easily modified. The instrument can also be used for spot readouts of optical density.
