BQ80S Microflow Variable-Speed Peristaltic Pump

Functions and FeaturesSimple 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.SpecificationsFlow range: 0.004-77 mL/minSpeed range: 0.1-80 rpmSpeed accuracy: 0.5%Speed resolution: 0.1 rpmPower supply: AC 100-240V, 50Hz/60HzPower consumption: < 10WExternal logic level control signal: 5V, 12V (standard), 24V (optional)External analog control signal: 0-5V (standard); 0-10V, 4-20mA (optional)External communication interface: MODBUS RS485Ambient temperature: 0-40 °CRelative humidity: < 80%IP grade: IP31Dimensions (L x W x H): 112mm x 96mm x 96mm (4.4 x 3.8 x 3.8 inch)Weight: 0.8 kg (1.8 lbs)BQ80S Suitable pump heads and tubing, flow parametersDrive typePump headchTubing size(mm)      Flow    rate(mL/min) per channelBQ80S(Pump heads notinter changeable)FZ101WALL:0.8-1 ID:≤3.17      0.05-40DW10-11WALL:0.8-1 ID: ≤3.17     0.005-32DW10-22WALL:0.8-1 ID: ≤3.17     0.005-19DW10-33WALL:0.8-1 ID: ≤3.17     0.005-32DW15-1113#14#16#19#25#     0.004-64KD10-11WALL:0.8-1 ID: ≤3.17     0.004-32KD10-22WALL:0.8-1 ID: ≤3.17     0.004-32KD15-1113#14#16#19#25#     0.004-77
