Application Note

Hach pH 4.01 buffer solution is a ready-to-use calibration standard for glass pH electrodes and compatible pH measurement instruments. This colorless aqueous buffer has a certified nominal value of pH 4.01 ±0.02 at 25 °C and is supplied in a 500 mL bottle. The solution supports multipoint pH calibration alongside suitable neutral or alkaline standards, improving confidence in measurements of acidic liquids. It is useful in water and wastewater testing, industrial-process monitoring, laboratory quality control, and instrument maintenance. The standard is traceable to NIST reference materials and can be used with Hach meters and other compatible electrodes. Its value refers to 25 °C, so temperature handling and calibration settings matter when comparing readings. The bottle contains calibration solution rather than a pH probe, sensor or testing instrument.
