Aiming for the top share in the world’s pH meter market, Horiba developed the F-50 Series, a key group of the first in the succession of products marketed to commemorate the 50th anniversary of its foundation, with concerted efforts drawing on its Group’s technical capabilities for planning, designing, and producing products―all on the concept of “providing easy and entertaining professional measurement systems for worldwide users.”
