Sirchie - Vinyl Photo Evidence Rulers

These rulers feature both English and metric measurements. They are printed on a flat-finish vinyl surface which eliminates photographic reflections and may be written on. Rulers are 6" (15mm) x 0.010" thick and are available in sets of 10.

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.
