Select from handheld, wall mount or bench top - or switch between them all. edge® is happy any which way. Simply plug in the electrode, then play.

Measurement is simpler, quicker and more accurate than ever.

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.
