The Accu-Chek Active blood glucose meter provides accurate readings easily and efficiently. With no code chip required for encryption, it is easy to use, with just two buttons to operate. In addition, you can double-check visually and match colors to ensure accurate results. When an insufficient amount of blood is applied, the Accu-Chek Active gives you a short period to reapply. It also allows you to monitor your glucose level before and after meals, and reminds you to test two hours after eating with a visual and audio reminder.
