On the back of the bag there is a table for correcting the buffer value depending on the temperature

Instructions for use:

Pour the contents of the bag into 250 ml of demineralized water (at a temperature of 25 ° C), stir with a plastic spoon and wait for it to settle Powder has dissolved Then calibrate the meter fully according to the instructions with a solution with a specific pH.

The pH meter should be calibrated with the buffer that comes closest to the expected pH of the solutions we normally measure. For example, if we normally measure acidic solutions, we calibrate the meter with a buffer with a pH of 4.01, when we buy alkaline solutions with a buffer with a higher pH.

Every pH measuring device should be calibrated regularly to ensure measurement accuracy. Meter calibrations should start with acidic solutions and end with alkaline solutions.
