How to Choose the Right Dissolved Oxygen Data Acquisition Terminal?

Dissolved oxygen data acquisition terminals, specifically designed for measuring dissolved oxygen content in water, are widely used in the fields of environmental protection, aquaculture, wastewater treatment, scientific research, etc. Dissolved oxygen measurement is crucial for monitoring water quality, ensuring the healthy growth of aquatic organisms, and optimizing industrial process control. Therefore, selecting the right dissolved oxygen data acquisition terminal is crucial to ensure the accuracy and efficiency of water quality monitoring.

Selection Points

Measurement Principle

DOP-6141 (Polarography): Based on electrochemical principles, it analyzes the concentration of chemical substances in the solution by measuring the current under the potential control of the solution.
DOF-6310 (Fluorescence): Based on the principle that the fluorescence intensity decreases with the change of analyte concentration, it is used to detect and quantify substances.

Stand Pressure

DOP-6141 stand pressure: 0.2 MPa
DOF-6310 stand pressure: 0.3 MPa

Temperature Compensation

DOP-6141 temperature compensation: 0–50.0 °C
DOF-6310 temperature compensation: 0–60.0 °C
