Principle
Measurement conditions are adjusted according to user requests by Electrode measurement of sample conductivity. Conductivity detector solution supports Electrode constant calibration. Measurement accuracy is ensured by temperature compensation mode (automatic or manual) and various pure water modes. The intelligence system manages the measurement process, data is automatically stored and output to external software is supported.
Applications
Laboratory water quality analysis, pharmaceutical water testing, electronic grade water monitoring, industrial process control, environment monitoring, pure water system management
Standards
GLP specification
Steps
1. Power on and select Measurement parameters
2. Set the reference temperature, temperature coefficient or TDS coefficient as required
3. Select Electrode Type and calibrate to store Electrode Constant
4. Set the temperature compensation mode and reading mode
5. Electrode immersion in sample begins measurement
6. Review the data and select the output report format
7. Transfer data to the computer via the RS-232 interface
Notice
• For accurate measurement of samples below 10 μS/cm, it is recommended to use a constant of 0.1/0 (with flow groove) Conductivity detector Electrode
• Electrode constants are properly calibrated and stored before operation
• Pay attention to the selection of temperature compensation mode to adapt to different Sample types
• Regularly check the effectiveness of the built-in standard solution
• Ensure stable interface connection during data transmission
User rights management requires setting passwords to ensure data security
