HDD Degaussers

The Proton T-4 produces a bi-directional field, which provides a 20,000 Gauss positive field and a 20,000 Gauss negative field. This results in a field spread of 40,000 Gauss (4 Tesla). The T-4 achieves this by using unique, patented “Reverse Polarity“ technology. Other degaussers may have either a positive or negative pulse, but only one. The T-4 has both and is fully automatic. This ensures complete and permanent erasure of your sensitive data. The T-4 will degauss the highest coercivity media available today and is projected to sanitize future media coercivities for many years to come. No other degausser compares.




•Listed on the National Security Agency’s Evaluated Products List (NSA EPL-Degausser) and complies with DoD requirements for destroying classified information on magnetic media.

•Software requires all parameters (capacitor voltage, switch, etc.) are present prior to the “Go” LED display. If any problem exists that will compromise degaussing, the “Go” LED will not display.

•Internal Gaussmeter option guarantees consistent performance by reporting the magnetic field strength of every cycle numerically on a blue LCD display. Also, has digital cycle counter and status display.

•Patented “Reverse Polarity” Electro Magnetic Pulse

(EMP) technology.

•Fully automatic operation: no drawer to open and close, simply insert media into top slot and push start button.

•Lightweight and portable design enables table top or floor operation.

Why Choose Proton’s T-4 Degausser?

Data storage technology is constantly advancing, so it is important to consider longevity when investing in a degausser. The Proton T-4 is built to last well into the future. How long will it be until your degausser is surpassed by ever-increasing media coercivity that requires higher or reverse flux fields to sanitize the data?


The T-4 has a 40,000 gauss spread, giving it the highest flux field (+20,000 gauss/-20,000 gauss) of any degausser available today. It utilizes a patented “Reverse Polarity” process, which creates a high field saturation that is unique to the T-4. Other degaussers may have either a positive or negative pulse, but only one. The T-4 has both, and it is fully automatic. This ensures complete and permanent erasure of your data and protects your sensitive information.


  • Available with 12-Volt battery option for all field and emergency use.
  • Light weight design allows operation in virtually any work space.
  • Optional deployment case with wheels.


Only allows one piece of magnetic media in the chamber at a time to guarantee uniform exposure to the effective magnetic field.

The T-4 does not need to rotate the media during the cycle because of its unique chamber design. This assures uniform field strength and magnetic depolarization at every angle.


T-4 cycle time is 45-60 seconds. Continual use decreases the cycle time because the capacitors charge and store energy from previous cycles. This reduces energy consumption. In data security there are no short cuts. The Proton T-4 guarantees the most thorough degaussing operation available.


Permanent magnets can also last a long time but are limited in their strength and are far heavier. Pulse degaussers are much stronger and less cumbersome. The Proton T-4 takes security one step further with its patented “Reverse Polarity” technology.


Before initiating the “Go” LED display, internal software checks capacitor voltage and power before each cycle, which guarantees that each degauss cycle deliveries sufficient strength and consistent performance. Proton’s T-4 degausser uses Electro-Magnetic Pulse technology (EMP) and is built to last a long time. Independent testing has shown no reduction in capacitor strength after 100,000 cycles. The National Security Agency/Central Security Service Evaluated Products List for Degaussers (EPL-Degausser) states that “…though listed in the EPL- Degausser, customers that acquire these products should have them re-tested periodically according to manufacturer’s recommendations.” Proton recommends testing the T-4 after 7 years of use or when 50,000 media devices have been sanitized. We also have an annual recertification program available.
