How to Calibrate a pH Meter - Testing Kit with calibration powders and standard solutions

In this video, I'm sharing how I calibrate my pH meter. It's a cheap one, so I don't expect it to be too accurate, but I wanted to share my process. To do a basic push button calibration for this particular pH meter, two points are needed, so you'll have to use two calibration powders (6.86 and 4.00). During the process, I wasn't able to get the calibration to be accurate to 0.01, but it is accurate enough for my needs. Since the pH meter measures electrical conductivity (EC) of the solution and then converts it via an algorithm to get the pH value, there's some inaccuracies as it heads towards the alkaline, high pH range (from pH 7-14). I kept this pretty simple and easy to follow, but if I was unclear about something, let me know in the comments below! Like what you see?
