Technical Parameters For Water Quality Monitoring

The technical parameters for water quality monitoring primarily encompass the following aspects:

Dissolved Oxygen (DO): The measurement range for dissolved oxygen typically spans from 0 to 20 mg/L, with the capability to extend up to 50 mg/L. The resolution is 0.01 mg/L, the accuracy is ±0.1 mg/L for the fluorescence method or ±0.2 mg/L for the electrochemical method, and the response time is less than 30 seconds (T90). For further details, please refer to the Huihuan water quality monitoring analyzer - dissolved oxygen.

pH Value: The pH measurement range is 0 to 14, with a neutral value at 7. The accuracy of pH measurements is generally high, allowing for precise determination of the acidity and alkalinity of water.

Conductivity: The measurement range and accuracy of conductivity are contingent upon the specific measuring equipment and calibration method used. Typically, the accuracy of conductivity measurements can achieve ±1μS/cm.

Temperature: The measurement accuracy for water temperature is commonly ±0.1℃.

Measurement Methods and Technical Indicators

Dissolved Oxygen (DO): Fluorescence and electrochemical methods are commonly employed for measurement. The fluorescence method offers higher accuracy, while the electrochemical method is well-suited for rapid on-site detection.

pH Value: The glass electrode method is used for pH measurements, ensuring high accuracy and repeatability.

Conductivity: The graphite quadrupole electrode method is utilized, making it appropriate for measurements under various water quality conditions.

Temperature: High-precision temperature sensors are employed for measurements to ensure data accuracy.
