Profile: Fortress Technology Inc. specializes in product design and engineering, the production of quality equipment. Interceptor DF uses a simultaneous multi-frequency operation that effectively processes the transmission and reception of multiple frequencies continuously over a broad spectrum. This model was developed with a divergent field technology, which is the metal detector to use multiple field directions. This greatly improves the detection of ultra-thin contaminants that are often encountered in processing lines. These innovative technologies facilitate a significant improvement in detection capabilities.
