The Actiwatch Spectrum actigraphy system incorporate high-quality biocompatible materials and well-engineered sensors - accelerometer, light and off wrist to provide 24/7wearability and accurate data collection. The Actiwatch Spectrum Starter kit (actiwatch Spectrum, communication dock and actiwave software) includes everything to get started with actigraphy.
Features
- Comfortable, aesthetic design
- Off-wrist detector
- Time and date indicators (like an actual wristwatch)
- Device status indicator (logging, not logging, on wrist, off wrist, successful marker push)
- Seven Data Channels: white photopic light illuminance, red, green and blue light irradiance, activity, off-wrist and event marking
- Moisture protection and increased resistance to environmental challenges (moisture, shock, dust, etc.)
- Backlit display Infrared communication to the dock/reader
- One-year battery life – changeable at factory
- Large memory (2 MBit Non-volatile)
- Faster communications and data-download rate
