n   Monitoring Focus

ü   Carbon Dioxide (CO2)

Indoor CO2 level is a universal accepted parameter for the condition of indoor ventilation and air quality.

u   Non-dispersive infrared (NDIR) CO2 sensor with more than 10-year lifetime

u   ABC self-calibration technology guarantees reliable CO2 measurement

u   CO2 range: 0~2000ppm or 0~5000ppm

u   Rapid response, high stability and consistency

 

ü Mix Gases (TVOC-Total Volatile organic compound）

VOC emitted from building materials, decoration materials and furniture, includes toluene, ammonia, H2S, formaldehyde and other harmful gases. Its necessary to real time detect these harmful gases. But it’s costly to use the professional instruments to detect each single gas. Also it’s possible to monitor for daily use. These gases exit in air for a long time and their volatilization level are different in different temperature and humidity,the reliability of such detection by a professional instrument for a single gas is very limited.

This multifunction IAQ monitor uses a mix gas sensor.It has high sensitive to kinds of volatile pollutant gases (VOC) such as ammonia, toluene,formaldehyde and cigarette smoke, alcohol, H2S, and carbon monoxide. So it is very suitable to monitor the general indoor air quality in real time and long term. The mix gases sensor responds quickly to any change of the concentration of such gases. Not only you may open windows for fresh air coming but also the monitor can control a ventilator/air-cleaning devise based on the indication and alarm.

u Built in the semi-conductor mix gases sensor

u 5~7 years life time

u High sensitive to volatile gases like ammonia, toluene, formaldehyde, sensitive to cigarette smoke, alcohol, H2S, etc.

u Small volume, lower consumption

 

ü   Temperature and humidity

Switzerland digital temperature/humidity sensor built in with high accuracy and stability. It also has compensation to CO2 and TVOC which makes the measurements more accurate by minimizing environmental effects.

 

 

               LCD Display

 

 

 

n Application

G01-CO2–B5 monitor/alarm is used to monitoring room CO2 and TVOC, as well as room temperature and humidity. It detects and monitors indoor IAQ level. It provides one on/off output to control a ventilator according with the CO2 or TVOC measurement or according with both of them.

It provides both buzzer alarm and three colors backlit switching alarm.

u   Hotel, exhibition hall, hospital, shop, restaurant, air port, train station, theater and other public places

u   House, villa, office, meeting room, classroom and other rooms

u   All ventilation systems
