BT101S Basic Variable Speed Peristaltic Pump

Peristaltic pump BT101S provides flow range from 0.00011 to 720 mL/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. With RS485 MODBUS interface, the pump is easy to be controlled by external device, such as computer, human machine interface or PLC.

Flow: 0.0001-720mL/min
Max: 4 Channels
SKU: BT101S Category:
