Essentials CO2 Monitor

Essentials CO₂ Monitor – With Temperature & Humidity Display

Monitor indoor air quality with precision using the Essentials CO₂ Monitor. This easy-to-use device features a high-accuracy NDIR (Non-Dispersive Infrared) sensor to measure carbon dioxide (CO₂) levels, along with real-time temperature and relative humidity readings.

Designed for both function and clarity, the large display provides:

• Real-time CO₂ levels

• Ambient temperature

• Relative humidity

• A clock

• A 24-hour bar graph showing CO₂ level trends

Smart Visual & Audio Alerts
Stay informed at a glance with a backlight that changes color based on CO₂ levels (green for normal, amber for elevated, red for high). You can also program an audible alarm to sound when CO₂ levels exceed your chosen threshold.

Customizable Display Options
Choose from seven backlight colors to match your space, or enable auto-dimming from 10:00 PM to 6:00 AM. You can also switch the backlight off entirely if desired.

Flexible Power Options
The monitor is powered via USB-C and can run from the included mains adaptor, a computer USB port, or a USB power bank.
