Real-time detecting CO2 level.
NDIR infrared CO2 module inside with four CO2 detection range selectable.
CO2 sensor has Self-Calibration Algorithm and 15 years lifetime
Wall-mounting
Special “L” series with 6 lights indicates CO2 level and makes CO2 level show clearly.
Provide a special model with an on/off relay output with a touch button to operate a fan control.
Design for HVAC, ventilation systems, offices, or other public places.
