The new series of air quality sensors! The sensors are designed to monitor the quality of the indoor air. They measure carbon dioxide, relative humidity, volatile organic compounds and the temperature in various combinations (carbon dioxide, carbon dioxide + relative humidity, VOC, VOC + relative humidity, relative humidity and relative humidity + temperature). The sensors have analogy outputs 0-10 V / 0-20 mA / 4-20 mA, it is possible to choose the option with the relay, power is 12 to 40 V DC or 14-30 V AC. Complete information about the NEW LINE sensors you can find in a list of products of our company.Read more »
What is the difference between the unregulated ventilation and the VAV ventilation system (From the English phrase: variable air volume) and DCV (from the English phrase: demand controlled ventilation)? The article describes the advantages and disadvantages of the functioning of the system.
VAV system is explained on the specific example in our company. It is described the initial regulation of the system and its operation during several years. Ventilation is regulated here by means of the air quality sensors, which are directly in our company.
Our company conducted a survey in kindergarten, school and office. We placed the air quality sensors to the classrooms and offices. Were were the values of carbon dioxide the worst? Maybe the results will not surprise you, but is it correct that children spend so much time in closed rooms where the air quality is often alarming?
The survey, which we conducted in the bedrooms shows that even in the night the air quality is not better, rather worse. This means that more than half of the day we breathe a poor quality air. Do you think it's okay?
Practical advice for placing of indoor air quality sensors. Install the sensor so that you ensure the most accurate measurement!Read more »
Indicator and the effective home alarm H450 for the presence of the deadly poisonous carbon monoxide (CO) that is produced by the incomplete or incorrect fuel combustion in boilers, fireplaces, stoves, gas stoves, or the incomplete chimney flue due to the improper installation or adverse weather conditions, will warn on time the user yet on the minimum concentration of this gas without color and smell and saves his life. Ensure your quiet sleep with the alarm H450EN!

Are you lost in the technical terms associated with measuring the concentration of different substances in the air? Sensors for measuring CO2, CO, volatile organic compounds, etc. operate on three fundamental principles from which lately is the most commonly used the NDIR principle. What does NDIR mean and how do the sensors work on this principle and on other ones?Read more »
Constantly turned on heating and above it an open window because there is an unbreathable air in the room is! Or closed window not to heat unnecessarily, but such unbreathable air that one can not be longer in the room. Do you know these situations? And do you know what smart ventilation is?Read more »
