BL-420S biological signal acquisition and analysis system
BL-The 420S scientific research biological signal acquisition and analysis system is the next-generation scientific research concept biological function experimental system launched by Chengdu Taimeng Software Co., Ltd. Its performance index and ease of use far exceeds any domestic and foreign similar products currently on the market, such as The stimulator of the editable waveform has not been implemented in any domestic product. Its 4-channel scanning speed is independently adjustable, and the system integrates various special data analysis functions. At present, no foreign product can be realized.
