As Ametris discontinues the sale of new ActiGraph GT9X Link wearable digital health technology (DHT) devices, existing GT9X Link customers will continue to have full access to device capabilities for their research purposes.
Ametris remains committed to providing service to GT9X Link users and their ongoing studies, including technical support. However, supplemental inventory will no longer be available. Below, we're answering common questions clients may have regarding this technology transition.
How will this affect my ongoing study?
Studies already using GT9X Link devices can continue to do so as normal.
What if I need to order additional devices or accessories?
Once the current inventory is sold, supplemental devices and device accessories will no longer be available.
What should I do if I was planning to use the GT9X Link for an upcoming study?
If you were intending to purchase GT9X Link devices for your research but have not yet done so, please contact your Ametris account manager. If you have already purchased the devices but your study has not yet begun, you can continue to use them as intended.
Do current GT9X Link users have to switch to a newer model for future studies?
You are welcome to continue using the GT9X Link throughout the lifetime of your devices. When it's time for you to purchase new wearable DHTs for your research, Ametris offers a full lineup of wearable devices that we believe can better serve your actigraphy needs.
What alternatives are available for the GT9X Link?
Researchers can accurately and remotely measure study participants' physical activity, sleep, and movement behavior with the ActiGraph wGT3X-BT and the ActiGraph LEAP.
Is GT9X Link data collected in an earlier study compatible with data from other ActiGraph brand wearable DHTs?
Ametris is committed to backward compatibility of ActiGraph brand wearables and has performed extensive testing to ensure a high level of data comparability across device models. The National Institute of Health (NIH) recently presented research that specifically compared data from five different ActiGraph models: Comparing ActiGraph CentrePoint Insight Watch, GT9X Link, and wGT3X-BT Accelerometers to NHANES 2011-2014 GT3X+ Devices using an orbital shaker.
Is ActiLife software compatible with other ActiGraph brand wearable DHTs?
ActiLife currently supports GT9X Link and wGT3X-BT. It also now supports retrieving accelerometer data (epoch only initially) from ActiGraph LEAP devices.
How can I retrieve data from additional sensors on ActiGraph LEAP?
In order to take full advantage of the multiple sensors available on ActiGraph LEAP, data must be collected through the CentrePoint platform.
What if I purchased a GT9X Link with an extended warranty?
Any device purchased with a standard 1-year or extended 2- and 3-year warranty will be covered with supplemental inventory reserved just for these devices. If GT9X Link device inventory is depleted your device will be replaced with a different device model of equal capability.
For more information about the GT9X Link, please contact your Ametris account manager or visit our Support Center.
