Preparation before use<br>1. Gently remove the protective bottle from the top of the electrode and store it for use. 2. Clean the white deposited salt on the outside of the electrode with deionized water. 3. In order to maintain an appropriate penetration speed, the liquid level in the tube must not exceed the end of the spiral glass tube, and at least 1 inch (2.5 cm) above the sample liquid level, and the electrode bulb end should be completely placed in the measured liquid during use. Let the bulb come into full contact with the liquid to be tested to make it produce an ion reaction effect. 4. Gently shake the electrode (just like shaking the thermometer) to remove air bubbles in the electrode. 5. Immerse the electrode in the pH electrode storage solution for 1 hour. If there is no electrode storage solution, add 1gKCl to 200mL pH7 buffer as a temporary electrode storage solution. When the electrode is not in use, it can be configured with a long-term storage solution to activate and protect the bulb end. The preparation method can add 10mL3.3kcl solution to 200mLpH4 buffer solution. [3.3KCL is saturated potassium chloride, the configuration method weighs 23 grams of potassium chloride and 100ml of deionized water] Appropriate amount of preservative<br>Second, the precautions when using the electrode<br>1. Use fresh buffer2. Open the electrode protective sleeve3. Measure the gap and rinse the electrode with deionized water4. Stir the buffer and sample: a) Always stir at the same rate; b) Stir first, then measure5. When preparing the pH electrode, rinse the electrode with distilled water before and after the measurement. Absorb excess water from the electrode tip with a linen-free cloth to avoid rubbing the electrode bulb, otherwise static electricity will be generated and interfere with the accurate measurement of pH.6. Make sure that the buffer temperature is the same as the sample temperature. If the sample temperature is different, use a temperature compensation probe for temperature compensation.7. Regularly check the electrode slope with the two-point calibration method. When the electrode reading drifts or the slope is lower than 92%, please refer to electrode cleaning to clean the electrode.<br>Third. Electrode maintenance<br>1. Electrode cleaningUniversal cleaning solution-Immerse the electrode in 0.1M HCl or 0.1M HNO3 solution for 15 minutes, then immerse the electrode in the electrode storage solution for 30 minutes.2. Liquid junction blockage (salt precipitation)Causes: hard water, mud, organic dirt, planktonic microorganisms, moss, etc. Attached to the seepage sand core around the bulb and PTFE, the external reference electrode cannot work normally.Solution:: Immerse the electrode (60°C) in hot water for 15-20 minutes; soak the electrode in a hot saturated KCl (60°C) solution for 20-30 minutes and cool to room temperature; soak the electrode in a pH 4 buffer solution for 20 to 30 minutes 30 minutes.Check for excessive crystals. If so, rinse the crystals repeatedly with deionized water to check whether the flow rate is normalIf not, soak the electrode (60°C) for 15-20 minutes in hot water; soak the electrode in a hot saturated KCl (60°C) solution for 20-30 minutes and cool to room temperature; soak the electrode in pH 4 buffer 30 minutes. Immerse the electrode tip in concentrated HCl for 5-10 minutes, rinse the electrode, and check whether the electrolyte flow rate is normal. If the liquid junction is still blocked, pull the liquid junction (do not touch the glass bulb)4. Precipitation of inorganic substances on the pH sensitive
