BT50S Microflow Variable-Speed Peristaltic Pump

BT50S microflow variable-speed peristaltic pump provides flow range from 0.00011 to 190 mL/min with variable pump heads and tubings. It offers not only the basic functions such as reversible direction, start/stop and adjustable speed, but also Easy Dispense feature. With MODBUS RS485 interface, pump is easy to communicate with external device, such as PC, HMI or PLC.

  • Flow Rate: 0.00011-190mL/min
  • Up To: 2 Channels
SKU: BT50S Category:
