Understanding CO2 Measurement Lutron GC-2028 NDIR CO2 Meter

Carbon dioxide (CO2) concentration is a critical indicator of air quality and ventilation effectiveness. The GC-2028 uses advanced NDIR technology, which provides several advantages over other sensing methods:

• Superior Accuracy - NDIR technology directly measures CO2 absorption in the infrared spectrum
• Long-Term Stability - Minimal drift in readings over extended periods of operation
• Specificity - Selectively measures CO2 without interference from other gases
• Durability - Robust sensor design for reliable operation in various environments

Typical CO2 concentration levels and their significance:

• 400-600 ppm - Fresh outdoor air levels
• 600-1,000 ppm - Acceptable indoor air quality
• 1,000-2,000 ppm - Complaints of drowsiness and poor air quality
• 2,000-5,000 ppm - Headaches, sleepiness, poor concentration, increased heart rate
• >5,000 ppm - Workplace exposure limit in many jurisdictions

Advanced Features Explained Lutron GC-2028 NDIR CO2 Meter

Altitude Compensation

CO2 measurements are affected by atmospheric pressure, which changes with altitude. The GC-2028's altitude compensation feature (adjustable from 0 to 9,000 meters) ensures accurate readings regardless of elevation by automatically adjusting calculations based on the programmed altitude value.

Data Management

The instrument's memory function records maximum and minimum values, allowing users to track fluctuations in CO2 levels over time. This is particularly valuable for assessing ventilation performance and identifying peak concentration periods.

Computer Connectivity

With both RS232 and USB interface options, the GC-2028 can connect to computers for data logging, analysis, and report generation. When paired with the optional SW-U801-WIN data acquisition software, users can create comprehensive records of CO2 and temperature measurements for compliance documentation or trend analysis.
