The choice of the second buffer depends on your application: if you measure values below pH 7, use pH 4 as a second buffer. If you measure values above pH 7, use pH 10 as your second buffer. Some of our pH meter use 3 points calibration, keep in mind to always start with pH 7 first and others after.
To use a pH meter, place a small portion of your solution in a beaker or test tube, rinse the probe of the pH meter, and then place the probe into your solution. Within seconds, the readout will tell you the pH. After taking your measurement, rinse the probe again and place it back in its storage solution.
