BRESSER CO2 measuring device Smile XXL with traffic lights and extra-large LED display

There are many reasons why people keep the windows closed in stuffy rooms: letting in cold air or insects, or simply forgetting to ventilate the room. This can result in elevated CO2 levels. Humidity is not only a concern for plant lovers. Without fresh air, rooms can get very stuffy, especially in closed spaces with lots of people. This can reduce the comfort level and affect your concentration. With the BRESSER INV CO2 meter with an air quality data logger, you can keep a close eye on the indoor climate in your own four walls or in classrooms, offices and other rooms. The device features an easy-to-read LED screen that simultaneously displays the CO2 concentration, temperature and humidity. In addition to current measurements, you can also view trends: trends in your indoor climate can provide important indications of deficiencies in your ventilation habits. The CO2 air quality meter features a recording function for this purpose: simply place the meter in your desired location and view the measured data on your computer. The required Windows software can be downloaded via the link provided. Flexible CO2 meter - prevents stuffy air If time is short and indoor CO2 levels are not at the top of your list of priorities, the meter features an alarm function that allows you to set your own CO2 limit. When this limit is exceeded, the alarm sounds to remind you to ventilate the room. When it comes to positioning, the CO2 monitor impresses with its flexibility: simply find the right spot on the wall or place it on a flat surface using the built-in stand so that it is clearly visible. The micro USB cable supplied is used for data transfer to your computer and - in conjunction with the power adapter - for a reliable energy source.
