Single parameter DO meter dedicated to testing Dissolved Oxygen. Using Hanna's latest technology and design, edge® DO can be adapted to suit your working method. Switch from portable to bench in the same procedure or clear the surface for easier working and hang on the wall. Results are fast and reliable. Combining high precision technology with the user-friendly dimensions and format of a small digital tablet, edge® is breaking new ground in electrochemistry. Cutting-edge design, capacitive touch keypad and an intuitive user interface are just a few of the great attributes that make edge® stand out as the world's first hybrid meter on the market.
