With the BZ26 CO₂ air quality monitor, you always know when it’s time to ventilate. It reliably measures CO₂ concentration, temperature, and humidity and displays all values in easy-to-understand, color-coded ranges with a clear comfort indicator. Visual and acoustic alarms warn you when limit values are exceeded, helping you protect health, improve well-being, and reduce the risk of infection – while avoiding unnecessary energy loss through excessive ventilation. Ideal for homes, schools, offices, and all rooms where people breathe, learn, and work.
