Metrologic's MS900 Series hand-held laser scanners provide unsurpassed versatility and adaptability. In these innovative scanners, Metrologic has engineered the best of two worlds: the increased depth of field, accuracy, and high performance of a laser with the durable construction and low cost of a CCD. The MS900 also has a unique patented infrared sensor and control scheme that provides fully automatic activation and operation for complete hands-free scanning. The MS900 can be used either as a hand-held scanner or fixed scanner because of its unique design. An operator can simply “wave” the scanner in a natural position across a bar code and the MS900 will scan automatically. This automatic operation increases worker efficiency and productivity by allowing faster throughput. This added operator comfort reduces the risk of repetitive strain injury. The versatile MS900 can operate as a “hands-free” scanner when placed in its flexible, fixed stand. An operator can present bar coded items to the MS900 for automatic scanning. Special patents also make it possible to program the scanner for short-range and long-range laser activation in either the hand-held or hands-free mode. The MS900 series consists of three models: the undecoded MS941; the standard decode MS951; and the MS961 decoded with high density code reading capabilities.
