Horiba USA pH Buffer Solution Kit 250 mL

Horiba USA pH Buffer Solution Kit 250 mL ea (4.01/7.00/10.01/KCl Reference) – 502‑S

The Horiba 502-S USA pH Buffer Solution Kit delivers a complete set of calibration standards for accurate and reliable pH meter calibration. Horiba formulates each solution to meet precise laboratory and field calibration needs, supporting pH measurement across acidic, neutral, and alkaline ranges.

This kit contains four 250 mL bottles of ready-to-use buffer and reference solutions:

• pH 4.01 ±0.02 at 25 °C – for acidic range calibration

• pH 7.00 ±0.02 at 25 °C – for neutral point calibration

• pH 10.01 ±0.02 at 25 °C – for alkaline range calibration

• 3.33 M KCl internal reference solution – for stable reference conditions during calibration

Technicians and analysts rely on this kit to help ensure consistent, traceable pH meter calibration that supports accurate measurement results across different sample types. The ready-to-use solutions help reduce preparation time and minimize calibration variability.

This kit suits laboratories, environmental teams, educational facilities, and industrial quality control departments that require routine pH calibration with trusted standards.
