Hello All,

Do you want to know hot to calibrate a pH meter? If yes, check this video.

1) Dip pH meter in distilled water and wipe it with paper towel.
2) Pour 250ml water in 2 beakers. Add pH buffer solutions in 250ml water filled beakers and stir it to dissolve.
3) Put the thermometer in the beaker and check temperature. Value of pH at different temperatures is mentioned on backside of the packet. Temperature was around 25 degree C.
4) Turn on pH meter, put in 6.86pH buffer solution and press calibrate button for 5 seconds. You will see the pH value (6.86) blinking on meter display.
5) Dip the pH meter in normal distilled water and clean it with a paper towel.
6) Similarly, put the pH meter in other solution, press calibrate again for 5 seconds and you will see value 4.01.
7) Clean again in distilled water and wipe with towel.

How often should we calibrate before checking ph of product

[roopashree]

While raising ph i accidently added more LYE solution. Ph increased to 7.8 while. required ph is 5. I then added citric acid and brought down the ph..
Does this affect the effectiveness of the active ingredient?

Do you do anything special to protect the probe?

Hello, can you please tell me where you got this ph meter from? Thank you 😊

After getting this meter I need to calibrate?
Then only I need to use to check the ph of serum?

[roopashree]

What happens if I calibrate the ph meter in the solutions that are not exactly 25° C. May be it's around 23. Will it be calibrated wrongly?

Please ma can I use normal tab water to calibrate if I don't have distilled water?

[ibrahimbader]

Mine always defaults to 4.01, even if i immerse it in 6.8 or 9.1 buffer solutions 🙁

Sorry but this is scam, after calibration of 6.8 if you press callibrate button normal it is shifted to 4 reading automatically in 6.8 medium all reading were pre coded
