Compliant with the guidelines established by the Ministry of Economy, Trade and Industry - Carbon Dioxide (CO₂) Monitor for COVID-19 Infection Prevention Ventilation Measures CO2RK-Lite.
Compliant with the guidelines established by the Ministry of Economy, Trade and Industry New Coronavirus Infection Prevention Ventilation Measures Carbon Dioxide (CO₂) Monitor MODEL: CO2RK-Lite (Riken Keiki Co., Ltd.) As a measure to prevent the spread of the new coronavirus, it is recommended to check that the indoor carbon dioxide (CO₂) concentration does not exceed 1000 ppm and to ensure proper ventilation. The CO2RK-Lite detects carbon dioxide (CO₂) and informs you of appropriate ventilation standards, thereby reducing the risk of infection. *The "Guidelines for Preventing the Spread of the New Coronavirus in the Construction Industry" issued by the Ministry of Land, Infrastructure, Transport and Tourism recommends the installation of CO₂ sensors as a standard for proper ventilation in break and rest areas. 【Features】 ■ Compliant with the guidelines established by the Ministry of Economy, Trade and Industry ■ Accurate measurement with a sensor that does not produce false positives ■ Does not react to disinfectant alcohol ■ Connects to smartphones via Bluetooth ■ Maintenance-free for 10 years
