BT103S Microflow Variable-Speed Peristaltic Pump

Functions and Features

• Membrane keypad operation, simple, convenient and durable.
• High-quality closed-loop stepper motor drive, accurate speed and smooth operation, allowing for high-precision flow transmission.
• Basic functions such as forward and reverse, start/stop, full speed, speed regulation, state memory (power-down memory).
• Parameters include running time, interval time, number of cycles, etc. to meet the needs of timed dosing, liquid dispensing, and flow testing.
• The slow stop and anti-drip function can effectively prevent liquid dripping when stopping.
• Key lock function to prevent misoperation.
• Streamlined plastic housing, easy to clean.
• Circuit board with layered paint process for dust and moisture-proof.
• Excellent anti-interference characteristics, wide voltage range, suitable for complex power supply environment.
• A variety of external control signals can be used to control start/stop, forward/reverse rotation, speed adjustment, and optocoupler isolation.
• RS485 communication, compatible with Modbus protocol, for convenient connection with various control devices.
• Support blocking alarm, leakage alarm (optional).
• A thermal printer can be connected for real-time printing of operating parameters (optional).
• Can be connected with a variety of high-performance pump heads.
