The Actiwatch Spectrum Pro Actigraphy offers all features of the Actiwatch Plus but with added score functionality. Two subjective scores can be collected either at a programed time or manually. An Audible and vibratory alarm can also be set to remind subjects to enter there scores.
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
- Battery life typically 55 days with 4 scores per day
- Large memory (32 MBit Non-volatile)
- Faster communications and data-download rate
