Notes in the daily maintenance of the online ph water quality detector:

1. Regularly clean the glass electrode, the cleaning cycle depends on the water quality. Recommended once every 7 days.

2. Regular calibration, the calibration cycle depends on the water quality. Once a month is recommended.

3. Before the pH meter is officially used, it must be calibrated by professional maintenance personnel according to the operation requirements.

4. The pH meter probe must be immersed in water. In the absence of water, it must be removed and the probe must be rinsed, and then immersed in clean distilled water for maintenance.

5. Before each re-use of the pH meter, it must be tested with a standard solution and calibrated according to the specified operating requirements.

6. When the pH meter display result shows abnormal sudden change, check whether the line is connected well. If the pH meter measurement result shows the maximum or minimum, check whether the probe is damaged and needs to be replaced.

7. When there is a relatively fixed difference between the pH meter measurement result and the chemical method measurement result, the probe should be cleaned. If the fault is still not eliminated, the instrument needs to be re-calibrated. If it still doesn't work, you can replace the probe with a new one.

8. Do not spray water directly to the probe part of the pH meter. Avoid debris in the drain from hitting the probe section. If it is found that there is debris attached to the probe part, it should be carefully removed and cleaned.

9. For contaminated pH electrodes, gently wipe the tip of the electrode with cotton dipped in carbon tetrachloride or ether. If it is found that there is slight rust on the outer wall of the sensitive glass film, the electrode can be immersed in 5%~10% (volume ratio) hydrochloric acid (the time should not be too long), and then use it after the rust is eliminated, but it must not be immersed in concentrated acid. In order to prevent the sensitive glass membrane from being seriously dehydrated and scrapped.

10. The pH glass electrode also has a service life problem. The quality of the electrode is different, and the life of the electrode is not the same. However, it can be used to measure the Nernst conversion rate of the electrode (the ratio of the measured value to the theoretical value is called conversion rate), to check the performance of the electrode, that is, to measure the Nernst slope of the electrode at different pH values. For conversion rates exceeding 100±20 % of the electrodes generally cannot be used.

The pH value of human blood, also known as the hydrogen ion concentration index, is a scale of the hydrogen ion activity in the solution, which is also a measure of the acidity and alkalinity of the solution in the usual sense. This concept was proposed by Danish biochemist Søren Peter Lauritz Sørensen in 1909. P stands for potenz in German, meaning strength or concentration, and H stands for hydrogen ion (H+). Sometimes pH is also written as pondus hydrogenii in Latin form. Normally, the pH value is a number between 0 and 14, when the pH<7, the solution is acidic, when the pH>When the pH is 7, the solution is alkaline, and when the pH is 7, the solution is neutral. The pH value of human blood is 7.34 - 7.45. Our blood is slightly alkaline under normal conditions, and because the body has the ability to automatically adjust the acid-base, it will not change greatly even under special circumstances. The blood of a healthy person is generally around pH7.35 (pH7 is neutral, above 7 is alkaline, below 7 is acidic), even if there is a change, it is just a difference in the second digit below the decimal point. However, of course people are fatigued due to labor, and 'fatigue' is a physiological phenomenon, and it can also be said to be a phenomenon in which the metabolites produced by the burning of substances in the body increase; this 'metabolite' is a kind of 'acid' (called acid). Lactic acid and pyroglucanic acid), this kind of acid increases, of course, the blood tends to become acidic, that is, the number of pH decreases, and acidic blood is harmful to the body and can cause various diseases. In other words, fatigue is the phenomenon that the blood tends to be acidic, and 'fatigue' is the return of the blood to its original state of being slightly alkaline. Whether a person can quickly restore the blood to slightly alkaline after fatigue depends on the strength of the body's ability to regulate acid-base; diabetics often suffer from fatigue: the body's ability to regulate acid-base is too weak, and the blood tends to be acidic. Therefore, our body always reserves sufficient regulating ability, so that the blood is not prone to acidity, and even if it has this tendency, it can be recovered immediately. The main role in regulating acid-base in the body is 'calcium wanderer'. In layman's terms, if calcium is sufficient in our body, the ability to regulate acid-base is strong.
