1. pH detection, display, and automatic liquid addition are integrated, which can adjust the pH of the solution through static or online detection.

2. It can control the addition of test solution based on pH value, and the peristaltic pump can operate independently for other experiments.

3. Touch integrated display screen, Chinese operation interface, displaying both control settings and measured values simultaneously.

4. Using PLC control to accurately control the speed of the liquid pump and adjust the liquid addition speed in real-time.

5. It has multiple control measurement modes: automatic, manual, stop and other liquid addition functions, which can be freely switched.

6. Low impedance high-precision customized pH composite electrode with fast response, suitable for pH monitoring under various working conditions.

7. The stepper motor controls the peristaltic pump to add liquid, with good controllability. The fluid only contacts the pump tube, not the pump body, and is pollution-free.

8. The sealed pipeline connection is composed of acid and alkali resistant liquid addition pipes and imported pump pipes, with a long service life.

9. The pH measurement and control accuracy is high, and the flow rate can be automatically adjusted. Users can set the appropriate flow rate according to the usage process.

10. It can avoid the physical harm caused by organic solvents to experimental personnel when adjusting the solution, and also improve work efficiency.
