This product is an air quality monitor that detects Carbon dioxide (CO2),Noise,Temperature, and Humidity. it combines sensors real-time monitoring of Carbon dioxide (CO2), temperature, and humidity on its display
Suitable for detecting CO2 concentration in industrial, agricultural and residential environments.
Control the ventilation system according to the monitored target value (CO2 concentration).
1. Carbon dioxide monitoring of various industrial and agricultural plants, workshops, greenhouses, clean rooms,
2. Ventilation control and environmental quality monitoring required for homes, villas, office buildings, meeting rooms,
classrooms and other fields.
3. Ventilation control and environmental quality monitoring in public places such as hotels, exhibition halls, hospitals, shopping
malls, bars, restaurants, airports, train stations, entertainment halls, and theaters.
4.Units that produce and use carbon dioxide gas, etc.
Non-mandatory reference rating:
a) 350 ~ 400ppm-usual outdoor air level.
b) 400 ~ 1,000ppm-typical value in well-ventilated living space.
c) 1,000 to 2,000 ppm-an air level that is inadequate, sleepy, and sufficient to cause complaints
d) 2,000 ~ 5,000ppm-stagnant, old, sultry air level. It is headache and drowsiness, accompanied by
inattention, decreased concentration, rapid heartbeat and slight nausea.
e)> 5,000 ppm-Exposure to it may cause severe hypoxia, resulting in permanent brain damage, coma and even death.

Please read the instructions carefully before using this device.
Please keep the manual handy for quick reference and troubleshooting.
Avoid covering the air intake areas during use to avoid inaccurate measurements.
Avoid use of solvents to clean the product as residual fumes will skew air quality readings.
Avoid water or other liquids near the product to avoid electrical damage.
Do not allow unauthorized modification or repair of this product.
1)The positioning sticker is attached to the position to be installed.
2)Punch a 6mm hole at the 2 marked positions of the positioning sticker and drive the rubber plug into the wall.
3)Drive in the screws, and pay attention to about 4mm exposed. Then hang the CO2 meter up.
4）Connect one end of the USB cable to the USB power adapter, and the other end （round connector）to the power input port on the side of the device(input voltage ：DC5V )
Under normal working conditions, don’t do any settings, just plug USB port to the power adapter and the DC
round head into the device. You can test the current CO2 value and temperature and humidity in real time.
During the first use, please Turn on device and keep more than 24 hours, the device will automatically calibrate. (Do not power off and restart halfway when calibration)
