- Sleep Efficiency
- Heart Rate R-R Intervals*
ActiGraph Link Features
Programmable Display
The ActiGraph GT9X Link features a programmable LCD window that can be configured to display date and time and/or provide real-time activity feedback such as steps and kcals, or it can be completely disabled.
Inertial Measurement Unit (IMU)
An integrated IMU containing a gyroscope, magnetometer, and secondary 3-axis accelerometer sensors provides raw position and rotational data for a variety of advanced applications, including inclination, gait analysis, and fall detection.*
Bluetooth® Smart
The ActiGraph GT9X Link is powered by Bluetooth® Smart technology and offers a variety of wireless features, including heart rate monitoring, proximity detection, and communication with ActiGraph’s suite of mobile applications for iOs and Android devices.
Wear Time Sensor
An advanced wear time sensor on the back of the device uses capacitive touch technology to automatically detect when a wrist worn device has been removed for simplified compliance monitoring and data cleaning.
ActiGraph Link Specifications
The ActiGraph GT9X Link captures and records high resolution human activity information using a solid state 3-axis MEMS accelerometer and our proprietary filtering algorithm. The ActiGraph GT9X Link is fully backward compatible with previous device models to ensure data comparability for our existing clients.
