Hanna Instruments pH 7.01 and 10.01 Calibration Buffer Sachets (2 x 20mL) (HI770710P)

HI770710P pH 7.01 and 10.01 Calibration Buffer Sachets (2 x 20 mL) by Hanna Instruments is a high-precision calibration set designed to ensure the accuracy and reliability of pH meters. This pack includes one sachet of pH 7.01 and one sachet of pH 10.01, each containing 20 mL of ready-to-use buffer solution. It is ideal for users who need a small quantity for single or occasional calibrations without purchasing a full multi-pack.

These solutions are essential for two-point calibration, which improves the accuracy of pH measurements across the scale. The pH 7.01 solution serves as a neutral calibration point, while the pH 10.01 solution is used to calibrate at the alkaline end of the range—especially useful in saltwater aquariums, hydroponics, and industrial systems.

Each sachet is individually sealed to prevent contamination and preserve freshness. The buffers are prepared using high-purity salts and deionized water under controlled conditions and are traceable to NIST Standard Reference Materials. They offer an accuracy of ±0.01 pH at 25°C, ensuring dependable and consistent calibration results.

Using the HI770710P sachets is simple. Open the sachet, immerse the pH electrode into the solution, and follow your meter’s calibration instructions. Be sure to rinse the electrode with distilled water between calibration points to avoid cross-contamination.

The compact and portable format makes this set ideal for fieldwork, laboratories, or small-scale applications. For hobbyists and professionals alike, having one sachet of each buffer avoids waste and lowers cost, while still delivering precise and reliable performance.

With Hanna Instruments HI770710P, you get trusted, high-quality calibration in a convenient, single-use format—perfect for maintaining accurate pH readings in any setting.
