Poor air quality is often the cause of discomfort or fatigue and reduces concentration and performance. This is due to an increased or excessive level of carbon dioxide (CO2) in the indoor air. Monitor spaces where people are present with the CO-60. The air quality is continuously indicated by different LEDs (green, yellow, and red). When the set threshold is exceeded, an alarm is triggered to signal that ventilation is needed. In addition to measuring CO2 concentration, the CO-60 also measures ambient temperature and relative humidity, displaying these values clearly on the LED screen. The device can be powered either via a USB connection or with the included power adapter. Ideal for workspaces, children's rooms, public buildings, schools, offices, etc.
