The Actiwatch 2 actigraphy system incorporates high-quality biocompatible materials, well-engineered lightweight sensors with light, activity and event channels to provide 24/7 wearability and accurate data. Actiwatch 2 Starter Kit (actiwatch, communication dock and actiwave software) includes everything to get started with actigraphy.
Features
- Comfortable, aesthetic design to help enhance patient comfort and increase patient compliance
- Large memory (1 Mbit)
- Three data Channels: Photopic white light illuminance, activity and event marking
- Welded case design to provide increased moisture, shock and dust protection
- 30 day life rechargable battery. Charged via docking station (USB or wall current)
- Replaceable bands – Able to use with hospital band
Whitle light illuminance as standard
