Principle
The PHBJ-260 pH meter detects the concentration of hydrogen ions in the solution through triple complex pH Electrode, which is converted into an electrical signal for measurement. The instrument uses intelligent algorithms to automatically determine the measurement endpoint, supports multiple reading modes, and ensures measurement accuracy through temperature compensation. Data can be transferred to a PC via USB interface for management and traceability.
Applications
Water quality testing, laboratory analysis, industrial process control, environment monitoring, education and research
Steps
1. Turn on the self-test to ensure that the instrument is normal.
2. Select Measurement mode (pH or mV) and resolution.
3. Carry out pH Electrode calibration, support 1-5 point calibration, and automatically identify the standard buffer solution.
4. Immerse Electrode in the solution to be tested and select the reading method (automatic, timed, manual).
5. Read and record measurement data.
6. Use data management capabilities to store, access, or transfer data.
7. Optionally connect the printer to print the result.
8. Clean Electrode after use, shut down or automatically shut down.
Notice
• Electrode in good condition before use to avoid damage.
• Use a standard buffer solution during calibration to ensure accuracy.
• Pay attention to the temperature compensation setting when measuring.
• Regularly check the battery power to avoid undervoltage affecting use.
• Keep instrument drying to IP65 Protection Rating.
• Use dedicated communication software for data transmission.
When storing data, pay attention to the capacity limit (500 sets).
• Avoid use in extreme temperature environments.
• Use standard accessories to ensure compatibility.
