Medical biosignal acquisition system Neurofax

for clinical analysisdiagnosticfor hospitals

Product overview
The EEG Junction Box JE-921 is an interface module for the Neurofax EEG system, offered in a 32-channel configuration with options up to 64–256 channels and available mini-junction boxes. It centralises EEG and physiological inputs to simplify clinical recordings.

Key features

• Multiple inputs: Records up to 25 EEG channels plus 4 additional channels configurable as monopolar or bipolar (EXG); 3 bipolar/DC inputs; 4 dedicated DC inputs; separate CO2 and SpO2 inputs for multimodal monitoring.
• Monitoring resolution: Sampling rate up to 1,000 Hz per channel for high temporal resolution recordings.
• Input characteristics: High input impedance and excellent common-mode rejection ratio (CMRR) to minimise noise and preserve signal fidelity.

Compatibility
Designed for integration with the Neurofax EEG system; available in multiple channel configurations and offered with mini-junction box options for flexible setup close to the patient.
