pH test analyzer with sensor
Note:
1. During the intermittent period of electrode use, please clean the electrode test end with pure water.
2. If the electrode is not to be used for a period of time, it should be rinsed clean, dried up the remaining pure water, and stored in the soaking solution.
3. After long-term use of the electrode, the slope and response speed of the electrode may decrease. The measuring end of the electrode can be immersed in 4% HF solution for 3-5 seconds or in dilute HCl solution for 1-2 minutes. After washing with pure water, soak in potassium chloride (3mol/L) solution for more than 24 hours to renew.
4. The electrode bulb should not be in contact with grease, especially organic silicon substances.
5. Before and after the measurement, the electrode should be cleaned with pure water to ensure the accuracy of the measurement. After the measurement in the viscous sample, the electrode needs to be cleaned with hot pure water repeatedly to remove the stick to the electrode bulb. Sample.
6. When not in use, keep the data interface and electrode interface clean, and cover the corresponding dust cap.
7. Please combine the matched pH electrode and ORP electrode in the operation and maintenance specifications.
