Sirchie - Scales in Macrography Photography

Footwear and Tire Track Impression Comparisons Tools - Sirchie

Macrography Photography. These scales are designed primarily for footwear and tire track impression comparisons. They are excellent for verifying perspective distortion.

The scales are printed on rigid vinyl plastic and feature exceptionally sharp division indicators. They also feature a glare-free finish for photographing in most lighting conditions (0.040" thick). Black on white on one side, white on black on the other.

Model PPS6000 is a combination of PPS600 and PPS601. Options available include 300mmx150mm, and 150mm. 

To ensure the accuracy of our forensic scales, Sirchie inspects, measures, and verifies them using three standard rulers that are calibrated annually by Precision Measurements Corporation.
