New coronavirus countermeasure ventilation CO2 sensor <Domestic manufacturer, made in Japan standards>

New coronavirus countermeasure ventilation CO2 sensor <Domestic manufacturer, made in Japan standards>

Equipped with NDIR sensors that comply with the Ministry of Economy, Trade and Industry guidelines, simply place the ventilation timing on the table; numerous domestic implementation case studies available.

In Japan, there are standards for CO2 concentration in living spaces, and from the perspective of legal compliance, it is necessary to adjust the indoor CO2 concentration to not exceed 1000 ppm. From the COVID-19 Countermeasures Promotion Office (Cabinet Secretariat) "Points for Preventing COVID-19 Infection" *Excerpt [If possible in restaurants, install CO2 sensors to monitor carbon dioxide concentration and maintain it below 1000 ppm through appropriate ventilation] is measurable. The first CO2 measuring device in Japan is the "CO2 Sensor/Controller/Monitor." The "CO2 Sensor/Controller" measures the indoor CO2 concentration and notifies you of the CO2 level to ensure a comfortable and energy-efficient living space. In recent years, the health risks posed by indoor CO2 concentration in highly airtight buildings have become a growing concern.

CO2 sensor "Logtta"

CO2 sensor "Logtta"

Visualize ventilation with carbon dioxide (CO2) concentration! By looking at the CO2 concentration, you can understand the state of ventilation.

"Logtta" is a CO2 sensor with a measurement cycle of 1 minute that displays ventilation conditions in numbers and colors. By adding a temperature and humidity sensor, it is also possible to display temperature and humidity. Humans exhale CO2 through breathing, and in a sealed room, CO2 concentration continues to increase. Good ventilation keeps CO2 levels below a certain threshold. It is used in restaurants, fitness gyms, daycare centers, tutoring schools, and offices. 【Features】 ■ Install a tablet to display ventilation conditions ■ Customers can view ventilation conditions on their own smartphones ■ Understand when ventilation is necessary ■ Anyone can see the ventilation conditions, allowing those who notice to open windows for ventilation *For more details, please refer to the PDF document or feel free to contact us.
