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. The pH 4.01 and 7.01 buffer solutions in quick and easy to use 20mL sachets are the most popular buffers used before analysing samples. Ideal for those requiring an accurate acid or neutral reading, particularly suitable for those working in water purification plants, the food industry, aquatics, and hydroponics, and in any environments where the pH is expected to be acid or neutral.
The single dose sachets are really handy with each sealed sachet holding just the right amount of solution. Each time a meter or electrode is calibrated using the Hanna sachets, it is like using a newly opened bottle of solution!
