G02-VOC monitor is specially designed to detect indoor air quality in offices and home environments. Its internal gas sensor has high sensitivity not only to VOC's such as toluene emitted from wood finishing and construction products but also to other air contaminants which are emitted by cigarette smoke, ammonia, hydrogen sulfide, formaldehyde, toluene. Its also sensitive to carbon monoxide, alcohol, natural gas and smell from peoples body. So it is more suitable for monitoring IAQ than other sensor which is only used for one kind of gas.

G02-VOC can be used as an alarm and a controller in ventilation system .

1.Real time monitor ambiance air quality

2.Japanese semiconductor mix gas sensor with 5~7 years long life

3.Gas detection: cigarette smoke, volatile gas like VOC, formaldehyde, toluene, ethanol,

ammonia, hydrogen sulfide, sulfur dioxide and other harmful gases

4.Monitor temperature and relative humidity

5.LCD can display IAQ level and temperature, humidity with three-color backlight to show different air quality

6.Preset warning point of buzzer alarm and backlight

7.Detection range: VOCs 0~30ppm, temperature 5~45, humidity 595%RH

8.1x on/off output to control a ventilator

9.220VAC or 24VAC/VDC power selectable; power adaptor available; desktop and wall mount type available

10.Perfect performance for residences and offices
