The pH buffer solution powder is used to calibrate the accuracy of the electronic pH meter.
The electronic ph meter has high accuracy, but after continuous use, it will become inaccurate. Therefore, the pH meter should be calibrated regularly.
Step 1: Open the packet pour the powder into a cleaning dry glass container.
Step 2: Add 250ml deionized water (or distilled water) to the container.(better a 250 ml calibrated flask)
Step 3: Stir until the powder has completely dissolved.
Step 4: Calibrate your pH meter.(rinse the meter by pure water before test)
(CAUTION: Not a drinkable solution! )
