The DS9900 Series is a true workhorse among barcode scanners. Thanks to its robust, one-piece design, it's incredibly durable and resistant to external elements. The patented, double-sealed optical system protects the scanner's "eye" from dust, dirt, and scratches, while its IP52 certification ensures that spills won't interrupt operations. This scanner can even withstand multiple drops from 1.5 meters (5 feet) onto concrete and 2,000 tumbles from 50 cm (1.6 feet) without a problem. This rugged construction guarantees the DS9900 Series will consistently perform reliably, even in demanding environments.
