 VOC gases (VOCs - Volatile Organic Compounds) includes a variety of organic chemicals, some of which may have short and long term adverse health effects. VOCs are emitted by a wide array of products including fuels, paints, cleaning supplies, disinfectants, pesticides, building materials and many more. VOCs are common to the chemical industry where various organic solvents are utilized in chemical processing. VOCs can be continuously monitored at low levels utilizing advanced PID sensor technology specifically optimized for industrial environments.
