Achieve accurate pH readings and check your meter and electrode is functioning correctly with Hanna buffer solutions. Available in convenient, ready-made pH values, Hanna has a certified value calibration solution with an accuracy of ±0.01pH @ 25°C for all requirements. pH 7.01 is ideal for those requiring an accurate neutral reading, particularly those working in water purification plants, the food industry, aquatics, and Hydroponics, and wherever the pH is expected to be neutral. Latest Hanna portable and bench microprocessor instruments are calibrated with pH 7.01.

• All solutions show a batch number, an expiry date, and the correlation table between pH and temperature
• Prepared to NIST standards
• Sealed with an air tight, tamper-proof seal to prevent any CO₂ from entering and causing a change in the pH buffer value
• Buffer solutions should be stored at 25°C, away from direct sunlight for accurate readings
