Lovibond NIST Traceable pH Buffer Solution Calibration Set – pH 4.01, 7.00 & 10.01 (3 x 500 mL Bottles)

Lovibond NIST Traceable pH Buffer Solution Calibration Set – pH 4.01, 7.00 & 10.01 (3 x 500 mL Bottles)

The Lovibond NIST Traceable pH Buffer Solution Set provides everything needed for accurate multi-point pH meter calibration. This convenient kit includes three certified 500 mL buffer solutions covering the most commonly used calibration points: pH 4.01, pH 7.00, and pH 10.01.

Each buffer solution is manufactured using standard reference materials traceable to NIST (National Institute of Standards and Technology), ensuring reliable and repeatable calibration results. The solutions are color-coded for easy identification and are suitable for use with virtually all pH meters, including instruments with automatic buffer recognition and manually adjustable calibration settings.

This complete calibration set is ideal for laboratories, water treatment facilities, environmental monitoring, industrial processing, educational institutions, and field testing applications.
