Document Examination Equipment - ACO Electronics
QDEWill - Representing ACO Electronics' Infra-Red and Ultra Violet Document Examination Equipment. The key to the solution of a document examination case often lies in detection of a small addition, alteration, erasure, obliteration, substitution or other anomaly that appears on a questioned document. Many of these pieces of evidence can not be seen with the human eye, even under high magnification. However, with the use of equipment such as the ACO Electronics QDX 430 and QDX 630B, the document examiner can reveal and demonstrate these occurences.
