Product Introduction
Japan Nicera CO2 Carbon Dioxide Sensor ModuleCO2-4K-3M Description:
Monitoring parameter carbon dioxide (CO2) indoor CO2 concentration, the CO2 sensor module CO2-4K-3M is currently the main parameter used internationally and domestically to measure indoor air ventilation status and air quality. It uses advanced infrared self-diffusion NDIR method to measure CO2, with fast response, high stability and consistency.
