Description
Overview
GAOTek basic variable speed peristaltic pump not only has basic functions such as start-stop, speed adjustment, full speed and direction, but also has higher speed accuracy. The tube to LCD, and the Chinese and English display is more intuitive. Added multi-stage timing operation and suction function, more convenient operation, and can easily connect and control other equipment through MODBUS protocol RS485 communication. The large torque stepper motor can adapt to various pump heads and support the cascade use of multiple pump heads.
