ActiGraph GT9X Link

The ActiGraph GT9X Link is a triaxial waveform accelerometer. It contains a primary triaxial accelerometer, gyroscope, magnetometer and a secondary triaxial accelerometer. It features an LCD window, wireless technology and is water resistant up to 1 meter for 30 minutes. It measures acceleration at a user-specified rate of between 30-100Hz and stores raw, non-filtered data in the units of gravity (g). It can also measure heart rate with a compatible wireless heart rate monitor.

ActiGraph devices may be worn anywhere on the body (wrist, waist, arm or ankle) using a strap.
