BT102S Microflow Variable-Speed Peristaltic Pump


It’s discontinued. Please see the new product BT103S.

BT102S microflow variable-speed peristaltic pump provides flow range from 0.00011 to 480 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: 0.00011-480mL/min
Max: 2 Channels
SKU: BT102S Category:
