COMET U8415 CO₂ Monitor with Indicator Light & Alarm

COMET U8415 – Battery-Powered CO₂ Monitor 0–5000 ppm with LED Traffic Light and Acoustic Alarm 

The COMET U8415 is a smart, battery-powered CO₂ monitor with an integrated NDIR sensor – an easy and effective solution for monitoring indoor air quality in schools, offices, conference rooms, halls, hospitals, theaters, or at home. High CO₂ levels lead to fatigue, loss of concentration, and headaches – the U8415 warns early using a three-color LED indicator and configurable acoustic alarm.

The maintenance-free dual-wavelength NDIR sensor with multi-point calibration measures precisely from 0 to 5000 ppm. The indicator provides clear status information: Green (0–1000 ppm – good), Yellow (1001–1400 ppm – moderate), Red (above 1401 ppm – poor). The alarm tone can be individually configured using COMET Vision software.

The U8415 operates autonomously with a long-life Li-Ion battery (duration up to several years, depending on settings) or optionally via an external power adapter. The large LCD display shows current CO₂ values, Min/Max readings, and battery status. The monitor is robust, easy to use, and comes with a traceable calibration certificate – guaranteeing maximum quality and accuracy.

The U8415 is a smart investment in healthier indoor air – enhancing well-being and productivity.
