Calibrating solutions like this are used when e.g. you are working with nutrient solutions: No matter if you are using it to calibrate (set) your measuring reagent, create contrast solutions to determine data by color comparison or if you want to check your measurements accuracy.
Especially when you are using a pH-meter you need pH calibrating solutions to re-calibrate your pH electrodes. Those electrodes tend to drift off after a while, which can lead to errors in measurement. That is why we recommend to re-calibrate your pH-meter in regular intervals.
