Room CO2 sensor - RACO2-U

The room CO2 sensor RACO is suitable for measuring air quality in residential and office spaces. The measurement is performed by the NDIR sensor within a range of 0 ... 2000 ppm. Analogue output signal (0-10 V, 4-20 mA). The standard series includes various measuring ranges. In addition, a passive temperature sensor can be connected. The sensor is designed for normal environmental conditions, aggressive gases can be harmful and damage the sensor. The location where the sensor is installed can affect the measurement accuracy of the sensor and therefore we recommend not to mount the RACO2-U near windows or doors.

Air Quality CO2 level in a room gives indication of likelihood of corona contamination

Recent research has examined the relationship between CO2 and the spread of COVID-19 in classrooms and offices. Scientists have developed a new model to predict the risk of infection with corona. They have done this based on the amount of CO2 present there. This model highlights the importance of proper ventilation in workplaces and schools. The model was developed by researchers from Imperial College London, the University of Cambridge and the University of Leeds.

Air Quality Clean air for World Animal Day

Animal Day, the day we put an extra spotlight on our dear dogs, cats, rabbits, guinea pigs, etc.! As much as we love our pets, we cannot deny that they produce foul odors, dander, hair and moisture, as well as emitting CO2. Both long-haired, short-haired and hairless animals create indoor pollution. These pollutants cause indoor air quality to deteriorate. Fresh air is incredibly important, both for you and your pet. Want to treat yourself and your pet more and not just on Animal Day? Treat your personal pet and yourself to a clean environment!

Air Quality How do I measure the air quality in my home?

How clean is the air in your home, really? With a simple check, you can find out in no time. Measuring the air quality in your own home is actually not complicated at all! With a CO2 monitor or particulate matter meter (sometimes also called an air quality meter), you can see straight away whether the air quality in your home is good (enough) or not. If it isn't, you immediately know that extra ventilation is needed. In this blog, we explain how you can measure the air quality at home quickly and easily, what healthy indoor air quality actually means, which substances can cause poor(er) air quality, and what the relevant requirements and regulations are.
