Sirchie - Photo Evidence Rules (Disposable)

These high-contrast photo rules are printed on 90 lb. index card stock with a non-adhesive back in contrasting black, white or gray for use on all color backgrounds. Lay next to developed prints and photograph with any camera. Sold in sets of 100 each.

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. Click here to see the Certificate of Calibration. This verification follows standards set forth by the National Institute of Standards and Technology.
