Cem DT-802 Air Quality Measurement Device, Carbon Dioxide Meter

• The CEM DT-802 Air Quality Monitor is a precise device for measuring carbon dioxide (CO₂) levels in the air in ppm, as well as ambient temperature and humidity.
• It can measure CO₂ levels up to 9999 ppm with high accuracy.
• The large LCD screen ensures easy readability of data.
• Equipped with a backlit display for visibility in low-light conditions.
• When CO₂ levels exceed 1200 ppm, a red warning light appears and an audible alarm sounds. The alarm can be silenced via the "ALARM" button below the screen.
• Pressing the "ALARM" button activates or deactivates the alarm feature.
• Upon startup, a countdown begins, during which the device stabilizes. No functions can be used until the countdown completes.
