Use SIRCHIE®'s 6" (15mm) vinyl scales when photographing evidence for precise measurement. The scales are 0.020" thick, and calibrated in both inches and millimeters with crosshairs at each end. The scales also feature a flat finish which eliminates reflections. Packaged in quantities of ten.
To ensure the accuracy of our forensic scales, Sirchie inspects, measures and verifies them using standard rulers that are calibrated annually.
