"Beaver Sensor" Infection Control! {COVID-19, Heat Stroke, Influenza}

"Beaver Sensor" Infection Control! {COVID-19, Heat Stroke, Influenza}

Measure the state of closed spaces and visualize safety! By measuring the concentration of carbon dioxide in the air, the ventilation fan will turn on when the set CO2 concentration is exceeded!

Control external devices for environmental management! ☆ Control external devices when CO2 concentration exceeds a specific value * Patlite, ventilation fans, broadcasting equipment... ☆ Notify the administrator via email! Send a notification email when the measured value exceeds the set value! * Temperature and humidity information * CO2 concentration is displayed as a numerical value and on a meter. Additionally, when the CO2 concentration exceeds the set value, a notification email is sent to a designated recipient. * If either the risk of heatstroke or influenza exceeds the set value, a notification email is sent to a designated recipient.

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.

How to Select CO2 Sensors to Avoid Failure <Domestic Manufacturers, Japanese Standards>

How to Select CO2 Sensors to Avoid Failure <Domestic Manufacturers, Japanese 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.

Please download and refer to the reference materials titled "Selecting CO2 Sensor Models to Avoid Failure." ■ Below is an introduction to the NDIR sensor-equipped "C.H.C Marvel 001." In Japan, there are standards for CO2 concentration in living spaces, and from the perspective of legal compliance and adherence to regulations, it is necessary to ensure that indoor CO2 levels do not exceed 1000 ppm. From the COVID-19 Countermeasures Promotion Office (Cabinet Secretariat): "Points for Preventing COVID-19 Infection" *Excerpt [In restaurants and similar establishments, if possible, install CO2 sensors to monitor carbon dioxide concentration and maintain it below 1000 ppm through appropriate ventilation.] The first CO2 measuring device in Japan is the "CO2 Sensor/Controller/Monitor."

High-precision CO2 sensor "eAir" that visualizes "secrecy"

High-precision CO2 sensor "eAir" that visualizes "secrecy"

Visualizing air quality in various locations. Making density visible to create a safe space. A trending CO2 sensor introduced on NHK and TV Asahi news programs.

● Preventing the "three Cs" (closed spaces, crowded places, close-contact settings) in conference rooms and stores to implement infection prevention measures. By accurately measuring and visualizing the CO2 concentration in the space, efficient ventilation can be achieved. It can also measure room temperature and humidity, providing reliable ventilation guidelines and air conditioning management—benefits unique to "eAir." ● No setup required. Ready to use right out of the box. eAir can be used immediately after being taken out of the box without the need for additional devices or settings. The CO2 concentration is clearly displayed with a dual indication of four-color LEDs and real-time numerical values. ● Even more convenient! Check CO2 concentration from a distance with app integration. By linking the app, you can monitor CO2 concentration on your iPhone or Android smartphone even when you are not on-site. By monitoring air quality from various locations, such as building management centers or while out, you can gain greater peace of mind. High-precision measurement with NDIR technology specialized for CO2 concentration. It allows for more accurate and quicker visualization of the three Cs with the CO2 monitor, enabling immediate actions such as starting ventilation.
