【High Precision NDIR Sensor】: The CO2 , CO3 detector use the most advanced NDIR sensor, accurately and quickly detect the CO2 concentration, also measure temperature and humidity in the surrounding air in real time.
【Sound and LCD Three-Color Display Alarm】: Three LCD colors indicates different CO2 ranges (400-1000PPM: Green,1000-3000PPM: Yellow, 3000-5000PPM: Red). When CO2 concentration is 1000-5000 PPM, the carbon dioxide detector will make a DI DI alarm sound.
【Temporarily mute or Turn off the sound function】: CO2 level is 1000-5000 ppm, the CO2 monitor tester will sound DI DI . When you know that this potential hazard exists, you can press the power button to mute the sound temporarily. If you don't need this carbon dioxide (CO2 ) sound alarm, you can directly enter the setting button to turn off the sound.
【Where to use】: Home, room, office, classroom, car, vegetable shed, warehouse etc.
