Audited Supplier AGn31 is a 4 in 1 CO2 monitor with Dual Beam NDIR technology and large LCD, which clearly displays the CO2, temp, RH and real-time clock. To save power and extend battery life, the AK -n31 darkens the LCD backlight automatically from 22:00pm to 6:00 am. It is ideal for monitor air quality inside buildings like residential, library, offices, schools, shopping mall and HVAC systems.

LCD Display:
| Back Light Mode | Backlight | Buzzer |
| Auto | The LCD screen backlight color changes with carbon dioxide concentration. <800ppm: green; 800ppm~1,200ppm: yellow; >1200ppm: red. The red threshold can be modified in AL | Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF |
| AL | There is no backlight in normal state, but when the carbon dioxide concentration exceeds the alarm value, the LCD screen backlight is red. The AL alarm value is preset to 1,000ppm, please adjust the alarm value according to the alarm value setting method. |
Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF |
| ON | The backlight is always on. Only backlight function, without any prompt function. Backlight color depends on selected color, see COLOR setting function. | Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF |
| OFF | The backlight OFF, no back light function. | Buzzer beeps every second when AL is exceeded. Until it is turned off (with mute key) Default is OFF |
