Product Description

· This product is an air quality monitor that detects Carbon,

  dioxide (CO2),Temperature, and Humidity;
· It combines sensors real-time monitoring of Carbon dioxide (CO2),

   temperature, and humidity on its display;

Considerations

· Please read the instructions carefully before using this device;
· Please keep the manual handy for quick reference and troubleshooting;

Precautions

· 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;

 

CO2 indicator：

· Green: 400ppm to 1000ppm;
· Orange: 1001ppm to 2000ppm;
· Yellow: 2001ppm to 3000ppm;
· Red: 3001ppm to 5000ppm;

Key operation

· Power button, Press to turn on/off;
· Up button, press to adjust;
· Down button, press to adjust(Long-press to open/close alarm sound);
· Set button, press to enter set CO2 alarm value;
· DC adapter input port;
· LED display;

 

Adjust screen brightness:

· After turn on, the device auto access the interface which can show CO2 current value,
temperature and humidity. In this state, press "2" button to increase screen brightness;

Press "3" button to decrease screen brightness.(with 6 level for brightness).
 

Set CO2 alarm threshold:

· After turn on, the device auto access the interface which can show CO2 current value,

temperature and humidity. In this state, when you press "4" button, the digits of CO2

would flash, then press "2" button to increase 100ppm CO2 alarm threshold, or press "3"
button to decrease 100ppm CO2 alarm threshold.(CO2 alarm threshold area can be set

to 800~2000ppm). After set well CO2 alarm threshold, press  “4" button to finish.

 

Close/Open alarm sound:

· Long-press "3" button and hear a "di" sound to open/close alarm sound.

(Factory default CO2 alarm threshold is 1000PPM)

· After you set CO2 alarm threshold well, when CO2 value more than CO2 alarm threshold
and keep rising, the device would beep sound.
· No alarm when the CO2 value drops; For example, you set CO2 alarm threshold to
1500ppm,once CO2 value more than 1500ppm and keep rising;

 

For example, CO2 alarm threshold value is 1500ppm, when CO2 Value is 4000ppm and on
the way drops, for example when it reach 3000ppm or 2000ppm, it wouldn't alarm.

 

Installation Notes:

· The positioning sticker is attached to the position to be installed;
· Punch a 6mm hole at the 2 marked positions of the positioning stickerand drive the rubber
   plug into the wall;
· Drive in the screws, and pay attention to about 4mm exposed. Then hang the CO2 meter up.
· 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 1A/2A).

Working method:

· 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.
 

Automatic calibration:

· 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).
