Lutron AQ-9901SD 6-in-1 Air Quality Meter with SD Card
Lutron AQ-9901SD Professional 6-in-1 Air Quality Meter with SD Card Data Logger
The Lutron AQ-9901SD is a comprehensive air quality monitoring system that measures six critical environmental parameters in one professional device. This patented, ISO-9001 and CE certified instrument features real-time SD card data logging capabilities, allowing you to capture, store, and analyze indoor air quality measurements with exceptional accuracy.Complete Air Quality Monitoring Solution
Monitor all essential air quality parameters with a single device:- Carbon Dioxide (CO2) - Measure concentrations from 0 to 4,000 ppm using reliable NDIR sensor technology
- Carbon Monoxide (CO) - Monitor safety levels from 0 to 1,000 ppm with galvanic cell sensor
- Oxygen (O2) - Track oxygen levels from 0 to 30.0% with galvanic cell sensor
- Relative Humidity - Measure from 10 to 95% RH using precision capacitance sensor
- Temperature - Monitor ambient conditions from 0 to 50.0°C (32 to 122°F)
- Calculated Parameters - Automatically display dew point and wet bulb temperature
Advanced Data Logging Capabilities
- Real-time data recording to SD memory card (supports 2GB to 16GB cards)
- No additional software required - data downloads directly to Excel for analysis
- Simultaneous recording of multiple parameters (CO2/O2/Humidity/Temperature or CO2/CO/Humidity/Temperature)
- Adjustable sampling rate from 2 seconds to 8 hours 59 minutes 59 seconds
- Manual data logging with location tagging (positions 1-99)
- RS232/USB computer interface for direct data transfer
