BT301S Basic Variable Speed Peristaltic Pump

Peristaltic pump BT301S provides flow range from 0.006 to 1600mL/min with variable pump heads and tubings. It has basic functions such as reversible direction, start/stop, full speed (for fast cleaning), adjustable speed. Dispensing function can easily repeat liquid dispensing by time or volume. With RS485 MODBUS interface, the pump is easy to be controlled by external device, such as computer, human machine interface or PLC.

Flow: 0.006-1600mL/min
Max: 1 Channel
SKU: BT301S Category:
