Freestyle Libre 2 box of 1 Sensor



The Freestyle Libre 2 Sensor is a small device that allows for self-monitoring of sugar levels. Diabetics must regularly measure their glucose level in order to limit the risks of hypoglycemia and hyperglycemia.



Today, the Freestyle Libre 2 sensor is designed to make your daily blood glucose testing experience better.

Simply place the sensor on your arm using the applicator provided. Once in place, the sensor can be stored for up to 14 days. Correctly applied, it fits perfectly and will accompany you in your daily life without bothering you, even during your sports activities. Waterproof IP27, it can resist to an immersion under one meter of water during 30 minutes. You can therefore keep it in your shower or bath without affecting its performance. You can also wear it when swimming in the sea or pool, making sure you respect its waterproof conditions

To measure your blood sugar level, nothing could be simpler, you will just have to bring the Freestyle Libre 2 meter close to the sensor to know your sugar level. Indeed, the Freestyle Libre 2 meter measures the level of glucose in the interstitial liquid and displays it within a second on its large touch screen or on your mobile phone if you use the dedicated application.

It is also possible to set glucose alarms to be alerted when the results are not within the predefined values.
