• CO2 monitor measures carbon dioxide concentration inside buildings
• Equipped with NDIR sensor with dual wavelength and multipoint calibration
• Measurement range: 0 to 5000 ppm
• Accuracy: ± (50 ppm +3% from reading)
• Measurement interval: 15 s with external power (optional), 2 min on battery power

The Comet U8415 is a CO2 monitor with built-in carbon dioxide sensor. The battery powered device with the option of external power is designed to indicate CO2 concentrations inside of buildings such as schools, conference halls, hospitals, offices, etc. The device is equipped with a maintenance-free and long-term stable NDIR sensor with dual wavelength and multi-point calibration.

Although carbon dioxide is invisible and odorless, increased CO2 content in the room leads to fatigue and decreased mental concentration. The level of CO2 concentration is indicated by the U8415 using three colors – green, yellow, and red. Changes in the indicated states are also signaled acoustically by a beep. The signaling method can be set by the user using the Comet Vision software (free full version included). 

LED Indicators:

• Green LED flashes: CO2 concentration 0 to 1000 ppm
• Yellow LED flashes: CO2 concentration 1001 to 1400 ppm
• Red LED flashes: CO2 concentration 1401 ppm or more
