The new ActiGraph GT3X-plus activity monitor provides physical activity measurements such as activity counts and vector magnitude, energy expenditure, steps taken, activity intensity levels, MET’s and more. An integrated ambient light sensor supplies valuable information on the subject environment. Unlike previous ActiGraph devices, the GT3X-plus collects data in raw format at a user specified sample rate up to 100 Hertz. Filtering and epoch selection are performed after data is collected, allowing users to process datasets multiple times at different epoch selections. The GT3X-plus has an inclinometer to determine subject position and identify periods when the device has been removed, and it can be worn during periods of sleep to measure the amount and quality of sleep. The water resistant GT3X-plus can withstand submersion at depths to 1 meter for up to 30 minutes. The GT3X+ can store over 40 days of raw data*, and its rechargeable battery is capable of providing power for 30 days between charges.

IMPORTANT:
GT3X+ devices have been fully tested and are guaranteed to work with Connectland USB hubs (model CL-HUB20005). Other hubs (like the Belkin F5U237P1) may cause the device to malfunction. Externally powered hubs are required.
