Compact laboratory peristaltic pump BT-S

for liquid dispensing

Introduction
The BT-S Series peristaltic pump is designed for applications requiring gentle, contamination‑free fluid transfer. Available driver models: BT101S, BT301S, BT601S. Standard hose length: 2 m.

Key features

• 128×32 LCD with Chinese/English switch, straightforward parameter setting and clear status display.
• Optional Lead Fluid APP for remote start/stop, speed control and timed operation; optional monitoring features (shutdown alarm, tubing replacement reminder).
• Delay start and delay stop functions; start/stop, reversible direction, full speed and adjustable speed with power‑down state memory.
• External analog speed control; external control signals can manage start/stop and forward/reverse with physical isolation; wide input range 5–24 V.
• External speed control signal type (voltage or current) selectable from control panel (0–5V standard; 0–10V / 4–20mA optional).
• RS485 communication interface, Modbus protocol supported; communication parameters configurable for integration with other equipment.
• Support for OEM/ODM parameter configuration; circuit board with conformal coating for dust and moisture protection.
• Wide input voltage range and strong interference immunity; ABS housing with compact dimensions.
