VOC Sensor

1. Real time IAQ detection and alarm;
2. High sensitive to VOC and other contaminative gases;
3. LCD displays VOC&temperature.

Gas detection

Highly sensitive to many harmful gases, such as harmful gases from construction and decoration materials, VOCs (like toluene and formaldehyde); Cigarette smoke; Ammonia and H2S and other gases from household wastes; CO, SO2 from cooking and burning; Alcohol, Natural gas, detergent and other bad smells etc.
