Feature

●【Accurate Detect】This detector adopt NDIR（non-dispersive infrared）sensor what is a new type of infrared sensor, It works quickly, stably and wont be affected by temperature or other conditions than outdated Chemosensor. It’s detection accuracy is ± (50ppm+5% reading).
●【Indoor CO2 concentration】This CO2 monitor can detect CO2, temperature and humidity. CO2 concentration affects our life, If the indoor carbon dioxide concentration is too high, you will feel drowsy, unable to concentrate, or even dizzy and wheezing. This CO2 detector is widely use in home, school, Factories, Hospitals, Hotels, Car.
●【Data Logger】Built-in storage for continuous data logging, you can track trend data up to 24 hours for co2 concentrations, temperature, humidity, and it display the Max &min value. The 3000 mAh battery inside allows you to record indoor air index for a long time.
●【Easy to Use】This professional air quality monitor is easy to use, long press the power button to turn on. Then fast press the power button twice to enter the setting interface to setting clock and time. Then you can use this CO2 detector normally.
●【Our service】Please be aware this air quality monitor is for home indoor place. We do recommend using the monitor as a stationary unit and focus on 30 and 60 minute mean values and overall environment quality indication because long-term monitoring, the real-time data exist instability. If you have any questions, please feel free to contact us.
