The Proton T-4 offers the most effective data sanitization on the market. This Degausser removes data from all magnetic devices, including Laptops, Desktops, Network Hard Drives, LTO, and DLT Tapes, and is listed in the National Security Agency's Evaluated Products List (NSA EPL-Degausser). Simply drop your magnetic media into the slot, push the button and the degaussing process will begin. In under one minute, the Proton T-4 eliminates all traces of your confidential and classified information. With automatic on/off operation, the Proton T-4 Degausser un-aligns magnetic fields within the media material, ensuring that prior data retrieval is impossible. The Proton T-4 produces a bi-directional field, known as "Reverse Polarity," which provides a 20,000 Gauss positive field and a 20,000 Gauss negative field. The Proton T-4 Degausser offers powerful degaussing features for hard drives up to 5,000 Oe and tapes up to 2800 Oe. These specifications are the maximum media coercivities available and the maximum coercivity available for NSA test purposes. With that said, the Proton T-4 will not be outdated anytime soon. This lightweight Degausser takes up little space and is perfect for tabletop or floor use. The Proton T-4 requires minimal training and is extremely user friendly. You can have confidence that the Proton T-4 will guarantee that the data on your high-security hard drives and tapes will be unusable.
