The EFR400M, a smaller version of our folding scales, is perfect when photographing evidence such as bullet casings, fingerprints, bone and glass fragments. Its rugged, black anodized aluminum construction allows it to be used indoors or out regardless of the weather. This metal construction will withstand many years of consistent use. Because the scales and angular measurements are precision laser-engraved on a metal structure,they are long-lasting and can easily become a permanent addition to your forensic tools.The EFR400M metric scale measures 34.29cm fully extended and 13.35cm folded.
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.
