BT103S Variable-Speed Peristaltic Pump

Product Introduction:

The BT103S variable-speed peristaltic pump is driven by a high-quality stepper motor, with a speed range of 0.1 to 100 rpm and a speed accuracy error of <±0.5%. Its single-channel flow rate ranges from 0.00011 to 500 ml/min. The pump can be remotely controlled via software, and its operating status can be monitored in real time. Equipped with an RS485 communication interface compatible with the Modbus protocol, the pump can connect to host devices such as computers, microcontrollers, PLCs, variable frequency drives, and human-machine interfaces via various signal modes to enable centralized system control.
