Indoor air quality is a comprehensive indicator that includes various low concentration indoor pollutants;
The Air3100R-VOC indoor air environment detection sensor is a gas monitoring product specifically designed for real-time monitoring of indoor air quality. It can detect gases including cigarettes (hydrogen and carbon monoxide), ammonia, H2S produced by office and home environments, and toluene emitted from wooden and building products. So it is more suitable for long-term monitoring of room air conditions than a single sensor, making it easier to control indoor related fresh air fan equipment;
Hotels, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, train stations, entertainment halls, cinemas and other public places;
Family, villa, office building, conference room, classroom and other places;
Various industrial and commercial places such as factories, workshops, warehouses, underground facilities, etc;
Other special places that require remote monitoring and control of air quality concentration;
