Precise pH measurements made easy: Ensure maximum accuracy and reliability of your digital pH meter with the high-quality calibration solution set for the standard values of pH 4.00 and pH 6.86. This product is the ideal choice for all users who value accurate measurement results, whether in aquaristics, hydroponics (nutrient solution control), laboratories, checking pool and drinking water, or in food production.

Why calibration is essential: The reliability of any digital pH meter directly depends on regular and correct calibration. Without using a precise buffer solution, your device's measurements can drift and become inaccurate over time due to temperature fluctuations, the natural aging of the electrode, or contamination. The calibration solutions provide you with a cost-effective and space-saving solution to create a fresh, highly precise buffer solution at any time.
