CONTEC KT88-1016 16-Channel Digital EEG and Brain Mapping System for Clinical Diagnostics

The CE CONTEC KT88-1016 represents a specialised digital electroencephalogram (EEG) and brain electric activity mapping system engineered for hospital neurology departments, clinics, and research facilities. Its core function is to collect brainwave signals via electrodes placed on the scalp, which are then amplified, digitally converted, and analysed by connected PC software. This process generates detailed electroencephalograms displayed with colour depth, aiding in the diagnosis and study of neurological conditions such as epilepsy, intracranial inflammation, cerebrovascular diseases, and brain tumours. The system combines high-precision signal acquisition with robust software analysis tools, including FFT (Fast Fourier Transform) and power spectrum analysis, to provide clinicians with a comprehensive view of brain electrical activity.

Features and Construction

The KT88-1016 is built around a set of core technical features designed for accuracy, flexibility, and user safety in a medical environment.

Signal Acquisition and Channels

This system provides 16 primary channels for EEG signal acquisition, with the addition of 2 optional channels for electrocardiogram (ECG) monitoring, creating a potential 18-channel setup. It employs a bioelectricity amplifier to distill brainwave signals, achieving an input impedance of ≥10MΩ and a Common Mode Rejection Ratio (CMRR) of ≥90dB to minimise interference. The sampling rate is fixed at 100 dots per second with 12-bit accuracy, and the system maintains a very low noise level of ≤5µV peak-to-peak. Patient safety is prioritised with a leak current of less than 10µA and a Class II, type BF applied part classification, supported by a professional isolation transformer and dual power supply isolation system.

Recording and Analysis Software

A key operational feature is the continuous recording time of up to 24 hours, facilitated by an integrated full-automatic calibration system. The accompanying PC software offers powerful playback functions where both the waveform amplitude and display speed (paper speed) are adjustable across multiple settings. A specialised subdividing timeline divides each second of waveform into 5 parts for meticulous review. The software includes digital filtering that can be set as required, an EEG signal clipping function to isolate and analyse specific sections, and an electronic frequency ruler for measuring period, amplitude, and frequency. Events like opening eyes, closing eyes, and flash stimulation can be marked with different colours on the waveform for easy reference during case playback.

Uses and Placement

The system is designed for specific professional applications and requires correct setup to function optimally.

Event or Professional Use

In clinical and hospital settings, the KT88-1016 is used for routine and long-term EEG monitoring. Its 10/20 international standard electrode placement system is the recognised method for consistent, reproducible results. The optional multifunctional USB flash stimulator allows for evoked potential studies, with flashing controlled manually or via automated, pre-set schemes during sampling. For enhanced monitoring, an optional USB camera provides synchronous video recording, allowing clinicians to browse the EEG waveform alongside the corresponding sampled patient video. The system's ability to export case files into standard EDF and BDF data formats facilitates academic exchange and further collaborative analysis.

Setup and Operational Environment

For proper operation, the device must be used within its specified environmental parameters: an ambient temperature between +5℃ and +40℃, relative humidity not exceeding 85%, and atmospheric pressure from 700hPa to 1060hPa. Power is supplied simply via a USB 5V DC connection. The system's compact dimensions of 186mm long, 135mm wide, and 89.2mm high, with a weight of 550g, make it suitable for use on a trolley or workstation. The included EEG bracket and aluminum block support the physical setup of the acquisition unit and electrodes.

Benefits and Buying Value

This system offers specific advantages for medical practices seeking a capable and flexible diagnostic tool.

Reuse and Low Maintenance

The digital nature of the system and its standardised data formats (EDF/BDF) ensure case files can be archived on media like CD-RW disks and re-opened for future review or research. The powerful case management function allows for quick statistics and research. The hardware is designed for reliability, with optoelectronic data transmission enhancing safety and the USB interface simplifying connectivity without requiring internal computer installation. The integrated automatic calibration reduces the need for manual technical adjustments before use.
