Our high - tech company, with more than 14 years of expertise since its founding in 2011, takes pride in offering an accurate CO2 detector that sets the standard for precision in indoor air quality monitoring. This detector is meticulously designed using state - of - the - art NDIR sensor technology, which undergoes a rigorous calibration process to deliver highly accurate CO2 concentration measurements. With a measurement range typically spanning from 400ppm (ambient level) to 5000ppm, it can achieve an accuracy of ±20ppm within the common indoor range, ensuring reliable data for a variety of applications. Whether it's in office buildings, schools, hospitals, or homes, the accurate CO2 detector provides users with peace of mind by precisely indicating the CO2 levels in the environment. The detector features a user - friendly interface, usually presented on a clear LCD screen that displays real - time readings, along with historical data and minimum/maximum values. To enhance usability, it is equipped with intuitive controls that allow for easy adjustment of settings, such as alarm thresholds. When CO2 levels reach pre - set limits, both visual and audible alarms are triggered, promptly alerting occupants to potential air quality issues. Additionally, the device may include features like data logging, enabling users to store and analyze CO2 trends over time, which is essential for understanding and improving indoor air quality. Constructed from high - quality materials, the detector is built to last and is compliant with international standards like CE, ROHS, and ISO, reflecting our commitment to delivering a product that combines accuracy, reliability, and safety.
