PH Combination Electrode JH-PH201
Application:Model E-201electrode is combined by glass electrode and reference electrode for measuring Ph value in water. It is widely used in chemical light industry, pharmaceutical industry, dye-works and scientific institute where pH value needs measuring.Operation and maintenance:1. Before measuring, electrode must be calibrated with standard buffer solution.2. Sensitive glass bubble is not allowed to touch with hard substances. Electrode wills no effective if any rubbing is made.3. When measurement finished, put electrode in the cap, this has a bit of KCL solution in it.4. Outer reference solution of combination electrode is 3 mol/L KCL solutions (Mix 20ml distilled water with 3 mol/L KCL). Solution can be poured from small hole under the cap.5. Plug of electrode must be kept clean and dry. Short circuit of two ends of the plug is prohibited.6. Electrode should be matched with pH meter that has high input impedance(≥1012Ω)7. Electrode mustn't be dipped in distilled water, protein solution or acid fluoride solution for long time. It mustn't' touch with organic silicon grease.8. If slope drops, dip sensitive bubble of the electrode in 4% HF solution for 3-5 sec. clean with distilled water, dip in KCL solution to make it renew. 9. If bubble is contaminated or liquid junction is blocked, sensitivity of electrode will be influenced. Clean with proper detergent.10. Flowing table is reference for detergent selection: | Contaminated Substance | Detergent |
| Inorganic metal oxide | Less than 1 mol/1 acid /M |
| Organic grease substance | Weak alkalinity |
| Resin substance | Alcohol, acetone, ether |
| Protein blood deposit | Acidity enzyme solution |
| Dyestuff substance | H2O2 diluted bleaching powder |
