FreeStyle Libre 2 glucose monitoring reader — a compact handheld device with continuous readings and optional alarms

The FreeStyle Libre 2 reader from Abbott is a glucose monitoring system designed for people aged 4 and older who require insulin. It provides continuous readings from the interstitial fluid with a simple, one‑second scan and stores eight hours of history for easy review, all without routine finger-prick calibrations in everyday use.

• Primary compatibility: Works with FreeStyle Libre 2 sensors and the FreeStyle LibreLink App for iOS and Android, enabling convenient mobile access to your readings.
• One‑second scans: Scan the sensor to view your current glucose reading, trend arrow, and an eight‑hour history, even through clothing.
• Optional glucose alarms: Set low and high alert thresholds to be notified when readings exceed your set range, helping you stay on top of daily management.
• Wear duration: Sensor designed for placement on the back of the upper arm and can remain in place for up to 14 days for continuous monitoring.
• Water resistance: Designed to withstand daily activities; sensor is water resistant up to 1 meter for 30 minutes, making showers and light swimming feasible.
