OMNI HCOM-CNJP002 Japanese-made Multifunctional CO₂ Concentration Meter, Black

This device displays the carbon dioxide (CO₂) concentration around the product in real time. Large, easy-to-read characters allow for instant understanding. In addition to carbon dioxide concentration, it displays five other indicators for creating a comfortable indoor environment: TVOC (total volatile organic compounds), HCHO (formaldehyde), temperature, and humidity, all in real time. The large, highly visible LCD displays the CO₂ concentration using both numerical values ​​and colors, allowing you to quickly understand the level of caution and when ventilation is needed. It displays green for CO₂ concentrations up to 600 ppm (GOOD), yellow for 600 ppm to 1000 ppm (OK), and red for 1000 ppm and above (POOR). When the red "POOR" light illuminates, ventilation is necessary, so please ventilate. For sick building syndrome symptoms such as eye irritation, runny nose, dry throat, and nausea, please check the TVOC (total volatile organic compounds) and HCHO (formaldehyde) levels. This product is manufactured and tested in Japan, accurately displaying carbon dioxide levels in the surrounding area.
