The Peenscan (Coverage Verification) Pens make the Peenscan process* of measuring uniformity and extent of coverage as easy as using a magic marker. Peenscan Pens provide a convenient method for applying a thin coating of tracer fluid to very specific areas of a part without the need for masking. This has proven useful during initial engineering set-up of a part for shot peening as well as for monitoring critical areas (gear teeth, for example) during production shot peening.
The Peenscan Pen is available with two fluorescent tracer fluids and selection of the appropriate fluid is dependent on the hardness of the metal and the intensity of the shot peening process:
- The Peenscan 220-2 pen should be used for softer base metals, softer shot and lower peening intensities.
- The Peenscan 220-6 pen should be used for harder base metals, harder shot and higher peening intensities.
* The Peenscan process was developed by Metal Improvement Company and has been found to be superior to using a 10-power glass in many applications.
