The TruCheck Laser USB's unique scanning head features a moving laser that automatically scans from top-to-bottom on a barcode. The system takes the 10 individual scans to instantly generate the overall ISO grade of the barcode. The moving laser removes all the influence of a human operator as the scan angle and distance are fixed to ensure accurate, repeatable results. The scanning head is contained in a compact, sturdy housing and attaches to your PC via a USB cable for incredible flexibility. The TruCheck Laser USB can easily be taken into a warehouse, or any manufacturing location. A guide plate makes it fast and easy to position over a barcode.
