Horiba Standard Solution pH 7.00 (514-7)

Horiba Standard Solution pH 7.00, 514-7

The Horiba Standard Solution pH 7.00 (Model 514-7) is a ready-to-use pH buffer solution designed for accurate calibration and verification of pH meters and pH electrodes. Horiba formulates this buffer to provide a stable and precise pH value of 7.00 at 25 °C, making it a primary reference point for neutral pH calibration.

This standard solution supports routine 1-point, 2-point, or multi-point pH calibration procedures. Because the solution comes fully prepared, users can perform calibration immediately without dilution or additional preparation, reducing handling errors and improving measurement reliability.

The Horiba 514-7 buffer suits laboratory analysis, water quality testing, environmental monitoring, industrial quality control, and educational applications. It works with benchtop, portable, and handheld pH meters, including Horiba LAQUA and LAQUAtwin series instruments.
