Tabletop CO2 monitor BS-CO2D-ST01 1 piece

The timing of ventilation is notified by sound and color. Carbon dioxide meter Uses NDIR (Non-Dispersive Infrared) sensors recommended by the Ministry of Health, Labor and Welfare This product is a tabletop measuring instrument that displays the clock, temperature, humidity and carbon dioxide concentration in the air, and visualizes the level of danger with colors based on the concentration and alerts with an alarm. When a CO2 (carbon dioxide) concentration is detected above a certain level (1,201 ppm or above), a two-stage alarm and four-stage color change on the screen will notify you when it is time to ventilate. The CO2 monitor's CO2 (carbon dioxide) detection method is the non-dispersive infrared absorption method (NDIR). The Ministry of Health, Labor and Welfare announced in 2020 that the standard value for carbon dioxide concentration is "Standard Guidelines for Reducing Infection Risk," which recommends maintaining a CO2 (carbon dioxide) concentration of 1,000 ppm or less, an indoor temperature of 17°C or higher, and a humidity of 40% or higher as ventilation standards to avoid situations with a high risk of mass infection. After connecting the dedicated USB power cable (included), you can carry it around and use it in your car or outdoors after charging (the maximum battery life is approximately 9 hours). As a measure against coronavirus infection, it is also suitable for everyday use in residential spaces where CO2 concentrations tend to be high, such as schools, offices, restaurants, and hospitals. *As a criterion for determining whether the required ventilation volume is being met, it is effective to use a carbon dioxide meter to check whether the carbon dioxide concentration in the room exceeds 1,000 ppm. *The alarm sounding value is only a guideline and does not perfectly meet the standards for infection control.
