Product Introduction:
The system adopts a true external structure. Suitable for both laptops and desktop computers. Interface with computer: USB2.0。 Due to the independent circuit board used for the internal A/D acquisition part of the system (inside the external chassis), no matter how the interface technology of the computer develops in the future, the instrument can adapt to the development of the computer by replacing the A/D acquisition module and corresponding software, and the instrument upgrade is very convenient. The stimulator adopts an optocoupler fully isolated system and 12 lead modes with international standards for ECG.
Independently develop system software.

Hardware technical specifications:
1. The instrument adopts an integrated anti-interference power supply with AC 220V. Except for the built-in transformer in the chassis, there is no need to connect any external transformer, ensuring that the instrument can display clear and accurate bioelectric signals without any external grounding wire during any bioelectric experiment. This ensures the anti-interference performance and accuracy of the device.
2. The instrument has 8 channels, all of which are multifunctional fully controlled isolated amplifiers. Each channel amplifier can be used as a bioelectric amplifier, blood pressure amplifier, bridge amplifier, as well as a spirometer, thermometer, etc. And each channel has independent hardware modules that are mutually independent, greatly increasing the anti-interference ability between channels, and also bringing great convenience to instrument maintenance and repair.
