Feature:1. CONCENTRATION DISPLAY WITH FLASHING LIGHT: Real time display of carbon dioxide concentration value per cubic meter, flashing light to display the interval level2. SMICONDUCTOR DETECT AIR QUALITY: Using semiconductor detection technology, which can determine air quality problems more accurately, very practical3. AUTOMATIC DETECT: press and hold the power button for 3 seconds to turn it on or off. After starting up, place it in a ventilated place for 20 minutes until the data is stable, and then place it in the place to be detected for detection.4. FAST DETECTION WITH STABLE VALUE: Small size with big function, 1S per time real time refreshing, fast detection can obtain relatively stable measurement value5.
