What is NDIR ? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced ...

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
