Hanna® Buffer Solution pH 4.01

Hanna® pH 4.01 buffer solution is used for the calibration, verification, and routine monitoring of pH meters and pH electrodes in laboratories, food production, water analysis, and technical quality control. The solution is ready to use and designed to provide stable and reproducible calibration conditions at acidic pH levels.

pH 4.01 is often used in conjunction with pH 7.01 for two-point calibration of pH instruments and is particularly relevant when measuring acidic samples such as food, beverages, fermentation processes, and process fluids. The ready-to-use solution reduces the risk of mixing errors and simplifies routine calibration both in the laboratory and on the production floor.

The buffer solution is temperature-calibrated in accordance with the standard to ensure greater accuracy at varying temperatures and is suitable for both handheld and benchtop pH meters.
