How calibration of pll meter is done?
Answers
Answer:
1. Examine the pH electrode
First, check the pH electrode for contamination or damage. If it’s damaged, then fix it or toss it. If it’s just dirty, then use the cleaning solution according to its directions. Whether we use acids, washing liquid, or alkali, choose a solution appropriate for your process and the contamination.
2. Flush the pH sensor
Next, flush your sensor with distilled water. We can do this, even if we didn’t have to clean it, to rinse away anything that may contaminate the buffer solution you’ll use in Step 3. After flushing, dab or pat away excess water with the paper towels. We should not generally rub it more: you might charge or damage the sensor.
3. Immerse the pH electrode
Fill a beaker with your first buffer solution, then immerse your electrode in it. It’s easy to just drop the sensor directly into the buffer bottle, but we can avoid contamination and extend the life of a buffer if we use the beaker.
4. Calibrate the pH meter
Now we can start your calibration/adjustment. Keep an eye on the stability of the value; an old pH meter might react sluggishly. When the value stabilizes, set the device to accept this calibration/adjustment point.
5. Rinse the pH sensor and repeat
Flush the pH sensor with distilled water again, then immerse it in another clean beaker with the second buffer solution.
