The Sensor automatically measures and continuously stores glucose readings for 8 hours. The Sensor Kit has two parts: a Sensor Pack and a Sensor Applicator. Once you have assembled the Sensor, you will apply it to the back of your upper arm. It has a small, flexible, 5mm-long filament that is inserted just under the skin. The Sensor can be worn for up to 14 days.
IMPORTANT: The Sensor is water-resistant in up to 3 feet (1 meter) of water. Do not immerse longer than 30 minutes.
