Lightning Powder Vinyl 6'' Ruler

Ideal for use in evidence photos, these vinyl scales are available in white, gray, and yellow for ideal contrast in nearly any situation. Measurements are in both inches and millimeters and crosshair circles at each end assist in photogrammetry corrections. The flat color and non-glare plastic reduce reflections. A blank area in the center of each scale can be used to write initials, case number or other pertinent information.
