Working principle and structure characteristic

The equipment uses the infrared obstacle detection method, scans the tested blood regularly, and automatically detects the sub-interface of red cells and plasma from time to time. The tested data will be converted into results of Wechsler by computer processing. This can be displayed on the LCD screen or printer and can also be transmitted through the serial interface to a computer.

The instrument makes up detection of the host (include infrared detection devices, computer control systems, thermal printer) and the adaptive power supply (SELV).

The instrument has a large display apparatus; the interface is a simple appearance and has a film keyboard operation. The operation is simple and convenient. The instrument has highly automatic functions which can work at any time and continuously detect.
