The Essentials CO₂ Monitor is a user-friendly indoor air quality monitor, which detects CO₂ levels using a Non-Dispersive Infrared (NDIR) spectroscopic sensor.

General Information

Its large-format display shows the real-time CO₂ level, ambient temperature and relative humidity, along with a clock and a bar-chart indicating how CO₂ levels have changed over the previous 24 hours. It can be set to give a green / amber / red backlight to indicate normal / raised / high levels of CO₂, and there is also a programmable audible alarm which will sound when the CO₂ level reaches a user-set threshold.
