Freestyle Libre Dev Sensor (1x1)

The FreeStyle Libre sensor is applied on to the back of the upper arm with a simple, disposable device called an applicator.
When the sensor is applied, a thin, flexible and sterile fibre is inserted just under the skin. It is held in place with a small adhesive pad.

To obtain a glucose reading, simply perform a quick, painless3 1-second scan of the reader over the sensor.
This scan gives you more information than monitoring with blood glucose test strips, without the need for finger pricks1.

Each scan over the sensor gives a current glucose reading, the last 8 hours of glucose history, and a trend arrow showing if glucose is going up, down, or changing slowly8.
