  1. Data logging up to 15,999 points
  2. Data can be saved to memory 
  3. 1-Key touch to activate the logging mode
  4. Real Time clock and Calendar
  5. Warning Carbon Dioxide Level from 1000-5000ppm 
  6. Super large LCD w/ 15° Tilt Angle & large digital readout 
  7. Indoor air quality level indication (Good, Normal, Poor)
  8. Display CO2 value, Air Temp & RH, Year-Month-Date, and Hour-Minute simultaneously
  9. Maximum /Minimum CO2 value recall Function
  10. Selectable °C and °F
  11. Stable NDIR (Non-Dispersive Infrared) for CO2 detection
  12. ABC CO2 Automatic Background Calibration (ABC) and manual CO2 calibration 
  13. Longtime drift compensation
  14. Bright LED visible indicates power is ON 
  15. Audible Alarm on both high limit & low limit (adjustable)
