The Hanna Instruments pH 7.01 buffer solution 230ml HI7007M is a calibration solution for meters at pH 7.01. It is ideal for those who require accurate neutral readings, especially in water treatment facilities, the food industry, aquatic and hydroponic systems, where the pH is expected to be neutral. Portable Hanna instruments and microprocessor devices are calibrated with pH 7.01.

Buffer solutions should be stored at 25°C, away from direct sunlight.

For proper maintenance of the meter or electrode, it is recommended to use Hanna cleaning solution along with a buffer for maximum performance. The pH 7.01 solution can also be used as an emergency storage solution.

Calibration solutions with different values are also available:

• Hanna Instruments pH 4.01 buffer solution 230ml HI7004M
• Hanna Instruments pH 10.01 buffer solution 230ml HI7010
