What value (number) represents an unsafe level of CO2?

Hi, when the CO2 concentration exceeds 1000ppm, you need to pay attention to indoor ventilation, at this time, the CO2 concentration is already high. When the CO2 concentration reaches 1200ppm, it means that the current air environment is relatively bad, making people feel tired and lethargic. When the CO2 concentration exceeds 2000, it means that the current air is seriously polluted. Hope this information can help you.

Wow, that co2 monitor looks great, how do i turn off the alarm?

Dear customer, you just need to double click the button of CO2 Monitor quickly and hear a beep, it means the alarm has been turned off, double click again to resume

What's the accuracy/margin of error of the CO2 measurement (not the resolution or range)?

Dear customers, please watch this video, we tell you in detail all the parameters of Langkou CO2 monitor and also provide the concentration range of CO2 and PM2.5 and their corresponding air quality conditions, any questions please ask us

My pm reading is stuck on 999, even if i take it outside, even if i turn off/on. is it broken? is there a reset?

Hi, when you are testing the PM reading, is there any obvious smoke next to it? When someone smokes or there is dense smoke around, the PM index will rise rapidly. If the air around the device is in good condition, it is likely that a sensor failure has caused the PM reading to be too high. Please contact me through the Amazon mail system for more effective and timely communication.
