IAQ is a comprehensive index, including room temperature, humidity, fresh air, and diverse air contaminants of low concentration. Monitoring IAQ is very important to guarantee healthy life and work. Air pollution caused by decoration, paints on new furniture, smoke from cigarette or cooker and life or office scrap has become an invisible killer of human life, especially to the infant, the pregnant and the old, it can also cause nerve disorder or weak immunity, which is a potential danger to health.
So the key point is to monitor and control the environment we live in, and make invisible pollution visible.
As there are many kinds of harmful gases in the air, it become really cost to monitor every single kind of air. It is recommended that CO and IAQ be monitored at home, and CO2, CO and VOCs in classroom and office.
G02-VOC monitor is specially designed to detect indoor air quality in offices and home environments. Its internal mix gases sensor has high sensitivity not only to VOC's such as toluene and formaldehyde from wood finishing and construction products but also to other air contaminants which are emitted by cigarette smoke, ammonia, hydrogen sulfide etc. It’s also sensitive to carbon monoxide, alcohol, disinfectant and other bad smells. So it is more suitable for monitoring IAQ than any other sensor that for a single kind of gas.
¨ Application
u Ambiance air quality detection and alarm
u Ventilation systems
u Air cleaning systems.
u Installation place such as bedroom, sitting room, study and dinner room, kindergarten, classroom, office, car, restaurant, and other public places.
