Bio-signal Acquisition System

Used for physiology, pharmacology, and pathophysiology teaching and research. It can acquire and record signals such as
bioelectricity, tension, and pressure, and analyze changes in biological functions. It is equipped with 4 sampling channels, 12-lead ECG channels, and 2 independent stimulation output channels; it features built-in data analysis and experimental marking, automatic sensor recognition, and real-time monitoring of temperature, humidity, and air pressure, offering rich functionality.
