Description :

-Introduction of a new digital peristaltic pump developed by DFRobot
-Integrates a PPM motor driver on the pump with a Gravity interface (PH2.0-3P)
-Control signal is compatible with standard servo motor and can be controlled with microcontrollers such as Arduino, Raspberry Pi, and micro: bit
-The tube in the pump head is made of BPT material, which is anti-acid and has a long lifespan
-Peristaltic pumps are a type of positive displacement pump used for delivering small amounts of fluid
-Can be used for quantitative delivery in a variety of applications such as science experiments, hydroponics, drip irrigation, tropical fish farming, and shrimp cylinder environment control
-Can automate a large number of titration experiments such as potentiometric titration, indicator-based colorimetric titration, and pH-based titration
Also has applications in industries such as food and medicine
-Note: Motor power consumption is large and an external power supply may be necessary
-Note: Long-term use without a medium may cause the tube to stick, but can be fixed by restoring the elasticity of the tube by hand.
