Good ventilation is considered good corona prevention for interiors. CO2 sensors help with air exchange, especially in autumn and winter. Regular and correct ventilation is important. While this is often not a problem in spring and summer when the outside temperature is pleasant, in the cold season you have to make sure that rooms do not cool down. Support is provided by CO2 measuring devices. Such measuring devices are particularly recommended for rooms in which several people are present. Basically, the devices warn of too much carbon dioxide - i.e. exhaled air, which can also contain potentially pathogenic aerosols. The devices indicate when it is time to ventilate at the latest. (For a complete and correct exchange of air, the window should be opened wide for several minutes. Burst ventilation is also more effective and more energy-saving than tilted windows). Our CO2 measuring device with data logger fulfills the following functions: • To monitor the CO2 concentration in buildings where people are present, e.g. Schools, offices, public institutions • CO2 measured value with LED traffic light display • Display of time, room temperature and humidity • Clear graphic with historical values ​​(minute, hour, day, week) • Max. Min. Function • Adjustable alarm • Logger function saves more than 1 million data records as a CSV file on the micro SD card (included) • Power supply via micro USB cable (included) TECHNICAL SPECIFICATIONS: • Measuring range CO2: 0-5000 ppm • Scope of delivery CO2 monitor, micro SD card, micro USB cable, operating instructions • Humidity measuring range: 5 - 95% • Temperature measuring range: 0 to + 50 ° C • Micro-USB power supply • Mounting for hanging or standing • Dimensions (LxWxH): 120 x 33 x 66mm • Weight 103 g
