The main system consists of a monitor, a signal amplifier/processor unit, a computer unit, and various accessories.
Brand and Model Information
- Device System Brand-Model: NIHON KOHDEN Neurofax
- Monitor Brand: ASUS
- Electrode Paste Brand-Model: NIHON KOHDEN Elefix V
- EEG Electrodes Brand-Model: CNSAC Gold Cup EEG Electrodes
Authenticity Assessment
The logos, labels, and overall build quality on the device and its accessories suggest that the products are original. The details on the labels and the print quality reflect professional manufacturing standards.
Usage Areas
This device system is designed for performing electroencephalography (EEG) and electromyography (EMG) recordings in fields such as neurology, sleep disorder diagnosis, and long-term epilepsy monitoring. It is specifically used to monitor brain electrical activity, detect seizures, and conduct sleep studies. The accessories, including the electrode paste and cup electrodes, are used to ensure electrode adhesion to the skin and signal transmission.
Quantity Information
The images show a total of 1 main device system (including the transport cart, monitor, signal amplifier, computer unit, and other modules), 1 box of NIHON KOHDEN Elefix V electrode paste, and 2 boxes of CNSAC Gold Cup EEG Electrodes.
General Condition and Physical Deformation
The general condition of the device is used, with slight dirt and dust accumulation observed on some surfaces. There are no significant scratches, dents, or cracks on the casing. No physical deformation is visible on the monitor screen. The wheels and metal components of the transport cart appear to be sturdy.
Mechanical and Electronic Components
No visible issues have been detected in the mechanical components of the device (transport cart, drawer, buttons). The outer casings of the electronic components are intact. Power buttons and connection points appear to be in good condition visually. The front panel of the computer unit features an optical drive and USB ports.
Accessories
The system includes one monitor, one keyboard, one mouse, one signal amplifier/processor unit, one computer unit, and various cables (power and data cables). Additionally, there is 1 unit of NIHON KOHDEN Elefix V electrode paste (400g) and 2 units of CNSAC Gold Cup EEG Electrodes (in 10-piece packs, with 150 cm cable length). The CNSAC electrode boxes bear an expiration date of “2025-02”. The device features various socket inputs (electrode connection points, USB ports, power inputs), which appear visually clean and intact.
Battery Status
There is no information or visual evidence regarding the internal or external battery of the device in the images.

Screen Analysis
The monitor screen is powered on and displays neurophysiological data such as EEG waveforms, a timeline (00:00:00), frequency information (Freq Disc), impedance check, and various channel information (e.g., C3-P3, Fp1-F7). The “Nihon Kohden” logo is located in the top left corner of the screen, and the “EEG-1200” model information is in the top right. The “ASUS” brand is visible at the bottom of the screen. The data on the screen indicates that the device is actively recording EEG or displaying recorded data.
Dimensions and Compatibility
There is no direct information regarding the specific measurements or size of the product in the images. However, the fact that the system is on a wheeled transport cart indicates that it is designed for mobile use and is of a size that can be easily moved within a standard hospital or clinical environment. The CNSAC electrodes are compatible with 1.5 mm DIN / 5 mm touch-proof plugs, making them compatible with most EEG and PSG systems.
Manufacturing Year
There is no concrete label or document regarding the manufacturing year of the device or its main components in the images. However, the CNSAC electrode boxes bear an expiration date of “2025-02”. This information indicates that the electrodes can be used until at least 2025 and were therefore manufactured before 2025. The general design and appearance of the device suggest that it is a modern medical device and may have been manufactured within the last few years.
Documents
No documents such as invoices, warranty certificates, or user manuals for the device are visible in the images.
Usage Duration
There is no information regarding the total operating hours or usage duration on the device screen or labels.
Existing Faults
No clear evidence of a fault, such as a broken part, error message, severed cable, or missing component, has been detected anywhere on the device in the images. The device screen appears to be on and functional.
Potential Fault Risk
The general condition of the device is good. No concrete situation that could pose a potential fault risk, such as severe wear, rust, or cable crushing, has been observed in the images.
