CEM DT-326 Air Quality and Carbon Dioxide Monitor is designed for air quality control and health monitoring by measuring carbon dioxide (CO2) levels in areas that require monitoring, such as factories, schools, offices, transportation routes, etc. The measured CO2 value is displayed on the LCD screen in ppm (parts per million).

• The device features an NDIR (non-dispersive infrared) carbon dioxide sensor.
• Indoor air quality is displayed on the screen as Good (0 to 800 ppm), Normal (800 to 1500 ppm), or Poor (>1500 ppm) in ppm.
• Easy-to-read wide screen.
• Displays carbon dioxide (CO2) concentrations, air temperature, and humidity simultaneously on the screen.
• Adjustable carbon dioxide refresh rate.
• Adjustable carbon dioxide alarm function in the 0-5000 ppm range.
• Low battery warning alerts you when the batteries are running low.

• Carbon dioxide (CO2) measurement range: 0 - 5000 ppm
• Temperature measurement range: -10 - 50 °C
• Humidity measurement range: 0 - 100 % RH
