Always precise: For reliable and exact calibration of your pH meter at the calibration points pH 4.00 and 6.86.
Easy to use: The buffer solutions are ready to use, pre-portioned in convenient sachets — just open and prepare the test solution.
Compatible with many devices: Use these common pH values for standardized calibration of your digital pH tester.
Versatile: Ideal for aquariums, hydroponics, laboratories, and pools. Ensure long-term reliability of your measurements.
Calibrate your instruments quickly and reliably for maximum accuracy in your analyses
Accurate pH measurements made easy: Ensure maximum accuracy and reliability of your digital pH meter with the high-quality calibration solution set for the common values pH 4.00 and pH 6.86. This product is the ideal choice for anyone who values precise results, whether in aquariums, hydroponics (nutrient solution control), laboratories, checking pool and drinking water, or food production.
Why calibration is essential: The reliability of any digital pH meter depends directly on regular and correct calibration. Without a precise buffer solution, your device’s readings can drift over time and become inaccurate due to temperature fluctuations, natural electrode aging, or contamination. These calibration solutions offer a cost-effective, space-saving way to prepare a fresh, high-precision buffer solution at any time.
