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

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

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

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

@@PeterPete The device only receives a signal from the electrode. He must "read" the signal correctly. During calibration, the device "learns to read the signal correctly".
