G02-VOC-B3 Series Room Indoor Air Quality Monitor Description
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.

G02-VOC-B3 Series Room Indoor Air Quality Monitor Features
• Real time monitor ambiance air quality
• Semiconductor mix gases sensor with 5 year life
• Gas detection: cigarette smoke, VOCs such as formaldehyde and toluene, ethanol, ammonia, hydrogen sulfide, sulfur dioxide and other harmful gases
• Monitor temperature and relative humidity
• Three-color (green/orange/red) LCD backlit indicating air quality at optimal/moderate/poor
• Preset warning point of buzzer alarm and backlight
• Provide one relay output to control a ventilator
• Modbus RS485 communication optional
• High quality technics and elegant appearance, best choice for home and office
• 220VAC or 24VAC/VDC power selectable; power adaptor available; desktop and wall mounting type available
• EU standard and CE-approval

G02-VOC-B3 Series Room Indoor Air Quality Monitor Application
• Ambiance air quality detection and alarm
• Ventilation systems
• Air cleaning systems.
• Installation place such as bedroom, sitting room, study and dinner room, kindergarten, classroom, office, car, restaurant, and other public places.
