Overview and Device Identification

The images show an electroencephalography (EEG) system used for measuring and recording the electrical activity of the brain. The system consists of Nihon Kohden brand main units installed on a trolley, a patient junction box, a computer, a monitor, a keyboard, a printer, and related accessories. It is understood that the device is generally used in a clinical or diagnostic setting.

• 1 x Pantum brand black printer
• 1 x white trolley with wheels and a keyboard tray
• 1 x pack of colored electrode cables, which appear to be new and in their packaging
• Interconnection cables required for the system’s operation

General State and Condition

The overall condition of the device set is assessed as used but in good condition. All components appear as a complete set, ready for operation. No significant wear or damage has been observed on the devices. In particular, the new electrode cables still in their packaging suggest that the device has been well-maintained or is being prepared for new use.

Physical and Mechanical Evaluation

No serious physical deformation has been detected on the device’s casing, screen, or other parts. The beige plastic casings of the Nihon Kohden medical units show a slight discoloration (yellowing), which is common over time with such materials; however, this is not a defect that would affect functionality. The mechanical components such as buttons, switches, wheels, and the trolley’s keyboard drawer appear to be solid and functional. There are no signs of crushing, tearing, or significant wear on the cables.

Label and Technical Information

The following technical information can be read from the label on the device’s main unit:

• Device Name: ELECTROENCEPHALOGRAPH
• Model: EEG-1200K
• Power Requirement: 220-240V ~ 50/60Hz, 700VA
• Manufacturer: Nihon Kohden Corporation, Made in Japan
• Copyright Year: The label includes the notation ©2021. This indicates that the device’s design or software belongs to this year and usually suggests that the manufacturing date is also close to this year.

Other labels show codes such as “V2-0231” and “V2-0237”, but it is not clear if these are serial numbers.

Potential Fault Risk

Based on the visual inspection, there is no evidence to suggest that the device carries a serious risk that could lead to a malfunction in the near future. The slight discoloration on the medical units is purely cosmetic. The cables and connection points appear clean and undamaged. As the overall condition of the product is good, no significant potential fault risk has been observed based on visual evidence. This assessment is solely a prediction based on visual inspection and does not substitute a technical test.
