Principle
The pH meter converts the pH value into an electrical signal through the composite pH Electrode measurement of hydrogen ion concentration in the solution, which is displayed after processing by the electronic unit. Support automatic identification of standard buffer solution for calibrating to ensure measurement accuracy.
Applications
Water quality testing, laboratory analysis, environment monitoring, industrial process control
Standards
GB 4.00pH、6.86pH、9.18pH
Steps
1. Boot self-test
Electrode calibration of 1-2 point pH using standard buffer solution
3. Electrode immersion in the solution to be tested
4. Read the pH value after stabilization
5. Manual temperature compensation as required
6. Clean Electrode and shut down after use
Notice
• Electrode integrity before use to avoid violent collisions
• Use a fresh buffer solution when calibrating to avoid contamination
• Electrode is fully immersed in the solution during measurement to avoid bubble effects
• Regularly check the battery level and charge it in time
• Use a soft cloth when cleaning Electrode to avoid damage to sensitive parts
• Use silicone protective cover during storage to prevent Electrode drying
