The FreeStyle Libre 3 Sensor

  • Our smallest, most discreet sensor yet2 that is worn on the back of the upper arm and continuously measures the glucose concentration in the body's interstitial fluid day and night.

    The sensor updates the glucose result up to every minute and sends it straight to your compatible smartphone.

    It can be worn for up to 14 days and is water-resistant so continues to work while you shower, swim or exercise3.
