These scales are 2" (50mm) wide and are printed on flat, pressure-sensitive label stock with a non-permanent adhesive back. Use them on vertical or horizontal surfaces. Fingerprints, traces of blood and bullet holes are easily measured for photographic purposes. Includes both English and metric measurements. Sold in rolls of 50 each.
To ensure the accuracy of our forensic scales, Sirchie inspects, measures and verifies them using standard rulers that are calibrated annually.
