I can understand to calibrate for a pH of 7 but cannot understand why use a buffer solution of pH 4! I'm sure one only needs to calibrate the meter at pH 7 and it's done!
So, some pH meters allow you to do a single point calibration but it is not as accurate. To get the best accuracy, you should do a 2, or even 3, point calibration as it essentially gives the meter more reference points to work from. In wine, we are measuring something acidic, so we use pH 7 and 4
@@PeterPete Most instruments are calibrated with one, or two, or three buffer solutions. If high-precision measurement results are required, calibrate with three buffer solutions.

Excellent.... I can't imagine that an animation thumb down such a great video! Thank you for posting this. Very helped
It has been really helpful...Thank you so much sir🙏 (from India)
whats the chemical name of the buffers that you had used?
Informative dear Sir
Really usefull sir 🙏
very precise and concise video!! excellent
What about other options available on pH meter?
Where can I buy just the electrode
Sir I have a question if you can answer
Do we need to do calibration every day?
Yes, it will certainly need to be done every time you switch the meter on and I would also do it every 10 or so samples
Thanks brother ❤️
amazing
Hello like your videos
Amazing vedio
Thank you sir ❣️
Thanks a lot!!
Thank you so much!!!!
Thank u
Noice!

@@scienceetc7958 so what you're saying is the meter doesn't know what acidity or alkalinity are or pH!

@@СервіснийцентрІнвестлаб so by using a number of buffer solutions one is 'programming' the device to know what acidity, alkalinity and pH are!
