Hanna Instruments is proud to introduce the world’s most innovative pH meter: edge ®.

edge’s groundbreaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world class R&D. edge is a single meter that can measure pH, Conductivity, and Dissolved Oxygen and is incredibly easy to use. We put a lot of thought into edge’s ease of use.
