BRESSER PM2.5 / PM10 Particulate Meter with Wireless Sensor

Endless meetings, urgent work emails, looking after the kids, cleaning the flat… during our hectic lifestyles, it's easy to forget about regular ventilation. Even though we know better: a high CO2 concentration can affect our health and wellbeing. The BRESSER CO2 air quality monitor Smile will show you when it's time to let some fresh air into your home or office. Simply have a quick look at the intuitive LCD display to keep an eye on the CO2 concentration, temperature and humidity. You don't need to worry about remembering what constitutes a critical carbon dioxide level - the intuitive graphical display with a linear scale and smiley face will show you the quality of the air in your surroundings. The measurements are precise, with high resolution and fast. Ventilation alarmThe practical carbon dioxide alarm reminds you when you need to let in some fresh air. If the default setting is different to your ideal indoor climate, you can configure your own limit up to a maximum of 5000 ppm. The alarm function can then be activated with a simple button press. If the preset limit is exceeded, the alarm will sound at a varying intensity depending on the CO2 concentration. The display will also show a flashing arrow symbol to remind you to open the windows. Humidity is also an important factor, as high humidity levels can cause mould to form. You can also set your own visual alarm for this reading so that you will know whether the air in the room is too dry or too moist. If you want to see more than just the current readings, there is also a practical memory function that displays the maximum and minimum values for the last 24 hours as well as the average values from the last 15 minutes and 8 hours for carbon dioxide concentration, temperature and humidity. The device is powered by a power adapter to enable continuous operation. The BRESSER CO2 Air quality monitor Smile - the perfect solution for busy fresh air fans! FEATURESSimultaneous display of CO2 concentration, temperature (°C / °F) and humidity Colour LCD display, clear and intuitive Graphical display of current CO2 concent Carbon dioxide alarm functions: Humidity alarm function Memory function High precision, high resolution, rapid response time Dimensions: 123 x 110 x 32 mm Powered by power adapter, long-term continuous operation possible DELIVERY CONTENTCO2 air quality monitor Power adapter Instruction manual

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.
