The customer's site is for circulating hydroponic cultivation. The nutrient solution is composed of a reasonable ratio of nutrient solution A, nutrient solution B and acidic buffer. Analytical instruments are required to detect water quality parameters such as pH and EC, and the data is transmitted to the back-end control system in real time. This enables data recording and analysis, as well as automated monitoring and regulation of the entire system. Solution

Water quality parameters such as pH and EC are detected through online analytical instruments, and the data are transmitted to the back-end hydroponic control system in real time in the form of analog signals or digital signals to realize automatic data recording and analysis and decision-making. The dosing pump is automatically controlled through the high and low limit alarm functions to realize the automatic supply of nutrient solution and ensure the balanced proportion of various nutrients in the hydroponic nutrient solution, thereby ensuring that the parameters of the nutrient solution are within a reasonable range, suitable for plant growth and development and effective Absorbed and utilized by plants to maximize yield.

1. Monitor the water quality of the nutrient solution in real time and continuously monitor the entire process to ensure that the nutrient solution meets the standards.

2. Built-in temperature compensation and free calibration program make measurement more accurate.

3. High and low limit alarms, automatically control the start and stop of the dosing pump, and realize automatic proportioning of nutrient solutions.

4. Output analog or digital signals, data collection is more convenient.

5. Large-range conductivity controller, wide measurement range and higher cost performance.
