FAQ :
【FAQ of AZ 7729 NDIR CO2 Temp + RH% Monitor】
Q1: What are the advantages of the NDIR sensor in the AZ 7729?
A: The Non-Dispersive Infrared (NDIR) sensor provides superior long-term stability and high specificity to CO2. Unlike low-cost IC sensors, it is not cross-sensitive to humidity or other volatile organic compounds (VOCs), ensuring professional-grade accuracy in diverse indoor environments.
Q2: How does the 3-color LED light bar help in air quality management?
A: The 22cm light bar provides an instant visual cue of CO2 levels. Users can identify air quality status from a distance—Green (Healthy), Yellow (Caution), or Red (Danger)—without needing to read the specific numerical values on the screen.
Q3: How do I ensure the CO2 readings stay accurate?
A: The device provides two calibration options to maintain the precision of its NDIR sensor:
*ABC (Automatic): It self-corrects sensor drift by tracking the lowest CO2 levels over 7 days. It is ideal for offices or schools that get fresh air at night.
*Manual Calibration: For spaces without regular fresh air (like 24-hour factories or greenhouses), you can manually reset the 400ppm baseline in fresh outdoor air using the touch panel.
