The Hanna Instruments pH 7.01 buffer solution 20ml HI7007P is available in 20ml sachets, making it one of the most commonly used buffer solutions.

pH 7.01 is ideal for accurate neutral readings, especially in water treatment facilities, the food industry, aquatic and hydroponic systems. Hanna portable instruments and microprocessors are calibrated with pH 7.01.

The single-dose sachets are convenient, as they contain exactly the right amount of solution. Each time a meter or electrode is calibrated with Hanna sachets, the quality of a new bottle of buffer solution is provided.

For proper maintenance of the meter or electrode, the use of Hanna cleaning solution and a buffer is recommended for maximum performance. pH 7 can also be used as an emergency storage solution.
