People spend 90% of their time indoors, where the presence of gaseous pollutants, - volatile organic compounds (VOC), - is significantly higher than in open spaces. In these high density environments, such as offices, schools, hospitals and in general in public places, especially in modern buildings, the exchange of air is scarce and favors the increase in the concentration of carbon dioxide (CO2) produced by people.
All this affects people's well-being by promoting health problems, a decrease in concentration and production capacity.
The KET-AIR-210 works according to the indirect method of measuring CO2, equipped with a sensor in MOX technology, measures the quantity of hydrogen and from that estimates the quantity of CO2. In addition, combined with the sensor that measures the percentage of Volatile Organic Compounds (VOC), allowing you to take the necessary measures to increase and improve the efficiency of ventilation and air purification.
The KET-AIR-210 is also complete with high precision Temperature, Relative Humidity and Light sensors, with an RS485 ModBUS RTU Slave interface.
The .DY version with display offers users a lot of information on the degree of thermal comfort present in the environment. The innovative zero-consumption e-ink display guarantees excellent readability and allows continuous display of the parameters.
The .TS version allows the user to set the desired degree of comfort.
KET-AIR-210 is equipped with an internal memory (.DL version) that allows to store more than 60,000 information in case of interruption in data communication, retransmitting them automatically as soon as possible.
Designed to easily integrate into supervision and energy management systems (BMS / BEMS) it provides a simple user interface. Suitable for use in public environments supports keyboard lock and limitation of active functions.
