BQ80S Microflow Variable-Speed Peristaltic Pump

 Functions and Features

• Simple operation, portable size, easy to install. Suitable for equipment as an ancillary device and for laboratory use.
• 0.5% high precision rotating speed control with 0.1 rpm speed resolution. Speed range 0.1-80 rpm.
• The lifetime of the built-in Pharmed BPT tubing is up to 12000 hours for continuous running.
• Four-digit LED displays working speed and control mode.
• Membrane keypad.
• Reversible direction, start/stop, adjustable speed.
• Time dispense function. Repeat dispensing by setting the dispense duration time.
• Plastic housing, embedded design to work independently.
• The circuit board with conformal coating makes it dust-proof and moisture-proof.
• External logic level signal can control start/stop, direction and dispense function. External analog signal can adjust the rotating speed. Signal is optically isolated.
• MODBUS RS485 interface, easy to communicate with external control devices.
• Optional footswitch or timer for dispensing fluid.
