Training Protocol
- Before and after use, the electrode should be cleaned with pure water to ensure the accuracy of the measurement. After the measurement using a viscous sample, the electrode needs to be cleaned with hot pure water
- Electrodes should be cleaned with pure water after intermittent use and not come into contact with oil and organic silicone substances.
- After a period of long-term use, the electrode can be cleaned 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 14 hours
