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